 1. About SHELDUS Version 19.0

SHELDUS Version 19.0 was launched on November 20, 2020. The database covers the period from January 1960 to December 2019. SHELDUS is a county-level hazard data set for the U.S. and covers natural hazards such thunderstorms, hurricanes, floods, wildfires, and tornados as well as perils such as flash floods, heavy rainfall, etc. The database contains information on the date of an event, affected location (county and state) and the direct losses caused by the event (property and crop losses, injuries, and fatalities) as well as insured crop losses (indemnity payments by the U.S. Department of Agriculture). Insured crop losses cover the period from January 1989 to December 2019. The database contains loss information for Puerto Rico, Guam, and other U.S. territories from 2000 through 2019.

SHELDUS is updated annually, generally during the month of November.

SHELDUS can be searched for the following hazard types:

  1. Avalanche
  2. Coastal
  3. Drought
  4. Earthquake
  5. Flood
  6. Fog
  7. Hail
  8. Heat
  9. Hurricane/Tropical Storm

Information on NCEI (formerly NCDC) Storm Data Preparation

Directive NWSPD10-16 describes the National Weather Service's process in estimating losses from meteorological and hydrological events. Please download the directive HERE. See below some important estimation facts quoted directly from the guidance document:

  1. On fatalities and injuries: The determination of direct versus indirect causes of weather-related fatalities or injuries is one of the most difficult aspects of Storm Data preparation. Determining whether a fatality or injury was direct or indirect has to be examined on a case-by-case basis. It is impossible to include all possible cases in this Directive. The preparer should include the word "indirect" in all references to indirect fatalities or injuries in the event narrative.

  2. On loss estimation: Property damage estimates should be entered as actual dollar amounts, if a reasonably accurate estimate from an insurance company or other qualified individual is available. If this estimate is not available, then the preparer has two choices: either check the "no information available" box, or make an estimate. The exception is for flood events. The Storm Data preparer must enter monetary damage amounts for flood events, even if it is a "guesstimate." The U.S. Army Corps of Engineers requires the NWS to provide monetary damage amounts (property and/or crop) resulting from any flood event. The Storm Data preparer is encouraged to make a good faith attempt to obtain or estimate the damage. Property damage estimates are very important for many users and should be obtained if at all possible. Estimates can be obtained from emergency managers, U.S. Geological Survey, U.S. Army Corps of Engineers, power utility companies, and newspaper articles.[..] The Storm Data preparer should use the table in Appendix B entitled Property Damage Estimates in determining monetary losses. This table would allow the preparer to estimate monetary amounts for damaged objects when timely communication is not possible with emergency managers or insurance adjusters just prior to Storm Data submission. It is suggested that the Storm Data preparer, in conjunction with local emergency managers, insurance adjusters, utility company representatives, and the U.S. Army Corps of Engineers, enhance the table to more accurately reflect values typically found in the local CWA. Typically, damage refers to damage inflicted to private property (structure s, objects, vegetation) as well as public infrastructure and facilities. [..] Crop damage information may be obtained from reliable sources, such as the U.S. Department of Agriculture (USDA), the county/parish agricultural extension agent, the state department of agriculture, crop insurance agencies, or any other reliable authority. Crop damage amounts may be obtained from the USDA or other similar agencies.

  3. On Storm Data sources: Some information appearing in Storm Data may be provided by or gathered from sources outside the National Weather Service (NWS), such as the media, law enforcement and/or other government agencies, private companies, individuals, etc. An effort is made to use the best available information, but because of time and resource constraints, information from these sources may be unverified by the NWS. Accordingly, the NWS does not guarantee the accuracy or validity of the information.

Information on USDA's Indemnity Payments

Indemnity information dates back to January 1989 and is currently unavailable for any prior years. See below some important facts quoted directly from the USDA RMA website (http://www.rma.usda.gov/):

  1. On how the Federal crop insurance program works: Federal Crop Insurance Corporation (FCIC) programs are administered by the Risk Management Agency (RMA), which underwrites crop insurance policies for hundreds of crops and livestock in the United States. Crop insurance policies are sold and serviced by private insurance companies. (..) RMA provides policies for more than 100 crops. (This number would be much higher if every insurance plan available for the crops insured in every county were counted.) RMA also conducts studies to determine the feasibility of insuring many other crops and is conducting pilot programs for some new crop policies in selected states and counties. Federal crop insurance policies typically consist of the Common Crop Insurance Policy, the specific crop provisions, and the policy endorsements and special provisions.

  2. On the indemnity amount: The total amount of the loss for the designated peril.

 5. SHELDUS Data Manipulation 

      1. Losses reported as a range and not exact dollar values.

        Whenever the original data source reports a loss estimate as a range, SHELDUS uses the lower bound of the range. For example, All NCEI (formerly NCDC) Storm Data estimates prior to 1994/95 were reported in logarithmic categories ($<50, $50-500, $500-5,000, $5,000-50,000, $50,000-500,000, $500,000-$5 Million, $5 Million-50 Million, $50 Million to 500 Million, $500 Million to 5 Billion). For example, for an event with a loss range of $5,000-$50,000, SHELDUS will return an event with a loss of $5,000.

      2. Losses for landslide events.

        Loss estimates were obtained from 2015 NWSI 10-1605 Storm Data, unless noted. If there was no basis for the loss amount, $99 was entered as the property loss, with a note saying the loss amounts were unknown.

      3. Losses output as per capita values.

        Economic losses (i.e. property and crop losses) are first adjusted for inflation to 2017$ and then divided by the current population of a county. Human losses (i.e. injuries and fatalities) are divided by the current population to arrive at per capita values.
        Note: For Rose Island, American Samoa (population: 0) and Northern Island, Commonwealth of the Northern Marian Islands (population: 0 since 2010), we assume a population of 1 to allow for per county capita calculations.

      4. Events reported for a region and not a singular county.

        SHELDUS distributes the losses for multi-county events equally across the involved counties - this applies also to injuries and fatalities. If there is detailed information on the location of fatalities and injuries, SHELDUS will reflect this and will not distribute the losses equally. For example, if hurricane damage of $1 million was reported for County A and County B together, SHELDUS will show a loss of $500,000 for County A as well as a loss of $500,000 for County B.

      5. Losses by NWS forecast zones and not by county name.

        SHELDUS resolves the forecast zone and translates it into county location. SHELDUS has recreated historic NWS forecast zone information and can accurately resolve forecast zones and changes in zone definitions and boundaries over time. If multiple counties belong to a forecast zone, losses will be distributed equally as outlined under #2.

      6. Losses reported for counties that no longer exist.

        SHELDUS georeferences losses according to the geography at the time of the event. SHELDUS has recreated changes in naming conventions and county zone boundaries. All losses that occurred in a historic county are marked with (*). The following historic counties exist in SHELDUS:

      7. Insured crop losses reported by month only.

        Whenever the original data source reports an indemnity payment by month only, SHELDUS assigns a time range spanning the entire month meaning the begin date of an event is reported as the first day of the month and the end date of the event is reported as the last day of the month.

 6. Aggregated Data Manipulation 

      1. Aggregation by Geography

        a. State

        All underlying raw data records within a state are summed. The returned loss information are state totals for property losses, crop losses, injuries, and fatalities.This information can be additionally broken down (a) by year (or month) to create annual (or monthly) state loss totals; and/or (b) by hazard type to create totals by hazard type for the state.

        b. County

        Losses are summed across all counties within a state and returned as county totals. All underlying raw data records within a county are summed. The returned loss information are county totals for property losses, crop losses, injuries, and fatalities. This information can be additionally broken down (a) by year (or month) to create annual (or monthly) county loss totals; and/or (b) by hazard type to create totals by hazard type for each county.

      2. Aggregation by Time

        a. Year

        All underlying raw data records within a year are summed. The returned loss information are yearly totals for property losses, crop losses, injuries, and fatalities. This information can be additionally broken down (a) by geography (state or county) to create annual state or county loss totals; and/or (b) by hazard type to create annual totals by hazard type.

        b. Month

        All underlying raw data records within a month are summed. The returned loss information are monthly totals for property losses, crop losses, injuries, and fatalities.This information can be additionally broken down (a) by geography (state or county) to create monthly state or county loss totals; and/or (b) by hazard type to create monthly totals by hazard type.

        c. Quarter

        All underlying raw data records within a quarter are summed. The returned loss information are quarterly totals for property losses, crop losses, injuries, and fatalities. This information can be additionally broken down (a) by geography (state or county) to create quarterly state or county loss totals; and/or (b) by hazard type to create quarterly totals by hazard type.

      3. Aggregation by Hazard Type

        All underlying raw data records are summed across the 18 hazard categories used in SHELDUS. In instances where a raw data event lists multiple hazard types as causal agents, the aggregation will distribute the losses equally among the involved hazards. This categorization of losses may produce hazard types that were not originally select in the database query.

SHELDUS Version 6.1 (released 08/2007): Loss data added for the year 2006.

SHELDUS Version 5.1 (released 02/2007): Loss data added for the year 2005. Complete revision of the year 1990. Matching of SHELDUS records to presidential disaster declarations (PDDs), GLIDE numbers, and named major disasters.

SHELDUS Version 4.1 (released 02/2006): Loss data added for August 1, 2004 through May 31, 2005.

SHELDUS Version 3.1 (released 03/2005): Loss data added for January 1, 2001 through July 31, 2004.

SHELDUS Version 2.1 (released 10/2004): Revision of tornado losses from 1960 through 1993 and 1995. Version 2.0 incorrectly overestimated property damage (tenfold) and underestimated crop damage.

SHELDUS Version 2.0 and below (prior to 10/2004): For events that occurred between 1990 and 1995, a loss threshold of $50,000 or higher in either property or crop losses was applied. This threshold equals NCDC's logarithmic category 1 = $5,000 to $50,000). From 1995 onwards, SHELDUS includes all property or crop damage-causing events reported in NCDC's Storm Data publications. This change in methodology was necessary, since the main source of raw data - the National Climate Date Center (NCDC) - changed its reporting procedures in 1995. During this year both categorical as well as exact dollar losses were reported by NCDC. Thus, the majority of records from 1995 onwards are exact damage figures that have been reported as such by NCDC and that have not undergone any post-processing by SHELDUS (exemption loss distribution of events affecting multiple counties). Additionally, NCDC also improved its spatial reporting system. Instead of reporting affected regions and distributing losses across the affected counties, NCDC moved to reporting losses on a county basis. Thus from 1995-2011, SHELDUS includes EVERY event that caused property or crop damage as reported by NCDC.
