The methods used to compile the COOP data presented on this page are varied based on the type of information. Below is a brief explanation of each product. This page is new and is still undergoing some construction. We would appreciate any comments or suggestions you may have. You may contact us at ... w-ind.webmaster@noaa.gov Please reference the COOP DATA PAGE as your subject.
All of the data presented here is provided by a large group of dedicated volunteers.
Coop observers are the behind the scene employees who have committed themselves to gathering vital information daily and providing it to the National Weather Service for use in our daily weather and hydrological forecasts. This information is also the foundation of the national climatic database which is used in all weather related scientific studies and programs.
Amateur radio operators are also a strong supporter of the National Weather Service in many ways. Their severe weather reporting and coordination efforts are critical to the operations of the NWS and safety of area residents. Across
It is difficult to be able to thank all of those volunteers personally. We would like to take this opportunity to acknowledge the excellent work they do and thank them all for their dedication to the NWS and their local communities.
DAILY COOP MESSAGES...text products for the past 7 days as depicted by the day of the week. These are produced daily at approximately 10:10 am each day. This product is derived from daily reports at our 167 cooperative sites across the state. These readings generally occur between 6 and 8 am and reflect data for the previous 24 hours. Some stations provide temperature, precipitation and snowfall data while others provide only precipitation and snowfall. Approximately 60 to 70 stations report daily with additional stations reporting when precipitation occurs. The data collection, product preparation and transmission to this web site are automatic.
DAILY CoCoRaHS MESSAGES...text products for the past 7 days as depicted by the day of the week. These are produced daily at approximately 10:10 am each day. This product is derived from daily CoCoRaHS reports from across the state. These readings generally occur between 6 and 8 am and reflect data for the previous 24 hours. The data collection, product preparation and transmission to this web site are automatic. More information on the CoCoRaHS program can be found at the CoCoRaHS website.
DAILY AMATEUR RADIO MESSAGES...text products for the past 7 days as depicted by the day of the week. These are produced daily between 9:30 and 10:30 am. This data is compiled from amateur radio operators across the state. Rainfall and snowfall are measured each morning, reflecting precipitation gathered during the previous 24 hours at 131 sites. These reports are sent to area collectors who compile the data into an email and send the information to the National Weather Service office in
MONTHLY / ANNUAL COOP PRECIPITATION TABLES ...text products from 2001 to current (last month) as depicted by year, presented in a table format. The table shows a listing of stations with monthly reports and a total of all months and a monthly average. Also shown is an average monthly total for all stations. This data is compiled at the end of each month from 86 coop sites in central
MONTHLY / ANNUAL COOP SNOWFALL TABLES ...text products from 2001 to current (last month) as depicted by year, presented in a table format. The table shows a listing of stations with monthly reports and a total of all months and a monthly average. Also shown is an average monthly total for all stations. This data is compiled at the end of each month from 86 coop sites in central
The graphical interpretation based on the method used, which is described below, may make some areas appear to have had more or less precipitation or snowfall than they actually have had. These maps are meant to present a general idea of precipitation and snowfall amounts across the depicted area.
The method of analyzation used is called "Kriging". This is an estimation procedure used in geostatistics using known values and a semivariogram to determine unknown values. It was named after D. G. Krige from . The procedures involved in "Kriging" incorporate measures of error and uncertainty when determining estimations. Based on the semivariogram used, optimal weights are assigned to known values in order to calculate unknown ones. since the variogram changes with distance, the weights depend on the known sample distribution.
DAILY COOP MAXIMUM TEMPERATURE MAPS...graphic representations for the past 7 days as depicted by the day of the week. These are produced daily between 10:30 and 11:00 am. This product is derived from daily reports at our 167 cooperative sites across the state. These readings generally occur between 6 and 8 am each morning and reflect data for the previous 24 hours. This graphic shows maximum temperatures readings from approximately 60 to 70 stations who report daily. The data collection is automatic but the mapping and transmission to the website are done manually.
DAILY COOP MINIMUM TEMPERATURE MAPS...graphic representations for the past 7 days as depicted by the day of the week. These are produced daily between 10:30 and 11:00 am. This product is derived from daily reports at our 167 cooperative sites across the state. These readings generally occur between 6 and 8 am each morning and reflect data for the previous 24 hours. This graphic shows minimum temperatures readings from approximately 60 to 70 stations who report daily. The data collection is automatic but the mapping and transmission to the website are done manually.
