Hourly Weather Observations

Hourly stations are official government reporting stations that produce a detailed hourly log for a specific day containing temperature, precipitation, winds, humidity, pressure, weather types, obstructions to vision, etc. These stations are usually from major airport weather stations in the USA.

Cooperative Weather Data

A cooperative station is a site at which observations are taken or other services rendered by volunteers or contractors who are not official government employees and who are not required to take or pass observation certification examinations. Equipment used at cooperative stations may be owned by the government, by the observer, or by a company or other government agency, as long as it meets official equipment standards. The records usually include a monthly log that includes a daily account of temperature extremes (participating locations) & precipitation, snow, and snow depth. Available for thousands of sites which are a part of the cooperative observing network in the USA.

Certified Weather Data

It is recommended that if you are presenting data for use as evidence in court, it should be certified by the Department of Commerce (Form CD-64) This is a two part certification (certification and authentication) under the Seal of the United States Department of Commerce with blue ribbon. This is the highest form of certification offered.
