The Spaceport Weather Data Archive is a repository of all locally collected weather data at Kennedy Space Center and Cape Canaveral Air Force Station. Note that weather radar data is excluded. Included in the Spaceport Weather Data Archive are: Weather Towers at multiple levels up to 492 feet, Electric Field Mills, Cloud to Ground and Inter/Intracloud Lightning Detection Systems, 50 MHz and 915 MHz Doppler Radar Wind Profilers including their Spectral data, Rain Gauges, Rawinsonde soundings, human surface observations, and other weather data.

The Spaceport weather data is updated every 60 minutes for certain instruments and as frequently as 15 minutes for other instrumentation. CGLSS (Cloud to Ground Lightning) data is updated every 30 minutes. Reference specific links to validate frequency of updates. Data is available 24/7 over a publicly accessible website.

The data is saved as is from the instrumentation and is not under Quality Control. Some data may be missing as a result of communications outages, power outages, routine maintenance and calibration. But the missing data may be available from other sources. Please confer with the KSC Weather Office, 867-0814, prior to using the data to ensure the most appropriate and most applicable use of the data. Frequently the weather office can provide technical advice to guide any research activities toward local operations at Kennedy Space Center and Cape Canaveral Air Force Station.

KSC Truth Station Precipitation Measurements
Tropical Rainfall Measurement Mission (TRMM) is a program from NASA's Mission to Planet Earth. A TRMM satellite was launched Nov. 27,1997 to measure tropical precipitation and its variation from a low-inclination orbit, providing a first opportunity to estimate the vertical profile of latent heat released through condensation of atmospheric water vapor.

Understanding the role of this released heat in driving the circulation of the global atmosphere is important to the studies of the global hydrological cycle and for testing climate models on a seasonal scale.

Ground based data from "truthing" stations, like Kennedy Space Center are used to verify and improve measurement and predictive capabilities which are part of the TRMM validation program.
