COOP and CoCoRaHs Observers Data

The methods used to compile the data presented on this page are varied based on the type of information. Below is a brief explanation of each product.  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 Indiana, the amateurs in conjunction with NWS have been gathering rainfall data since 1980 as the Indiana Wet Net. This additional information has been especially helpful during periods of heavy rain when rivers and streams start to rise. The Amateur radio operator's information is now included in the CoCoRaHs messages.

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.

GRAPHIC MAPS

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.   

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.
