| SEARCH INPUTS |
Following are the search inputs needed to make an e-Hail™ search. Below this
table, there is another table that provides an explanation of the report output
information.
|
| DATE RANGE |
| Start Date:
|
Earliest date for record search. January 1, 1996, is the default
value as this is the earliest data available for the online search, but the
date can be changed by the user. Contact Haag Engineering Co. at 800-527-0168
for a custom search if you need data prior to 1996.
|
| End Date: |
Last date for record search. Default value is today's date minus
two days (e.g. 2 days ago), but the date can be changed by the user. The latest
six to nine months of data has not been certified by the National Climatic Data
Center and is considered preliminary as it will be marked in the report with a
"P."
|
| LOCATION SEARCH METHOD |
| By Zip Code: |
Five digit zip code for the location of interest. If the zip code
covers multiple cities, you will be asked which city is your location of
interest. The centroid (population-based geographic center) location of the zip
code will be used as the center of the search.
|
| By Decimal: |
If you know the latitude/longitude coordinates for your search
location, they can be inputted directly. The coordinates must be in decimal
degrees.
|
| By Degree/Minute: |
Latitude and longitude coordinates are listed on some maps or
tables in degrees/minutes. The system converts degrees/minutes to decimal
degrees by multiplying the minute portion of the location by 1.667, and uses
the result as the decimal portion of the latitude or longitude. Example:
Latitude 34 degrees 30 minutes. 30 x 1.667 = 50. Use 34.50 as the decimal
latitude coordinate.
|
| MINIMUM HAIL DIAMETER |
The default value, "All (0.75+)" will provide all hail reports in the database,
but this can be limited by the user to only list hail reports larger than a
specified size. The database generally lists only hail reports ¾-inch in
diameter or larger (National Weather Service severe size criteria.)
|
| PDF REPORT OUTPUTS |
Following are brief explations for the output data found on the e-Hail™ PDF
Reports.
|
| Final (F) vs. Preliminary (P): |
Data certified by the National Climatic Data Center (NCDC) is
listed as final data (F). Data not yet certified by NCDC provided through the
Storm Prediction Center (SPC) is listed as preliminary (P). The latest date of
final data is listed above the hail reports.
|
| Time/Date/Zone: |
The date and time of the reported hail event. Time typically is
given as local standard time (no adjustment for daylight savings time).
Preliminary data is given in Central Standard Time (CST) only.
|
| Location: |
The city or locale of the hail report with county and state
included. If either type of latitude/longitude search is used, the location may
read, "Unspecified" unless an exact Zip Code centroid is matched. Often there
are more details provided regarding the location in the remarks section of
individual records.
|
| Coordinates: |
These will be the latitude/longitude paired coordinates for the
specified search.
|
| Prop. Damage: |
An estimated amount of property damage caused by the storm as
reported by the Storm Data publication of NCDC. The source and quality of the
damage information varies. A blank in this column indicates that no damage
information was provided or that it was estimated that there was not
significant damage, but the lack of a number in this column does not guarantee
a lack of damage from the event. The damage figures typically are listed by
thousands (2 K= $2,000) or millions (5 M= $5,000,000). Occasionally, the damage
estimates are listed by county or are written into the remarks section.
|
| Remarks: |
Text remarks prepared by the local National Weather Service
offices that provide additional details about the storm event or damage caused
by the storm. The remarks may contain information unrelated to the hail report,
such as tornadoes, wind damage, flooding, etc. that may have occurred from the
same storm event in the specific hail report.
