The Spaceport Weather Data Archive provides a fully searchable database of weather data gathered at Kennedy Space Center (KSC) and the Cape Canaveral Air Force Station. Not only can the user easily retrieve data and download it, but the user can also view graphically the weather data on a map overlay. The data are updated every hour for certain instruments, and as frequently as every 5 minutes for others. Data is available 24/7 over a publicly accessible Web site. The data is used by researchers to validate launch commit constraint criteria, and to ensure safe operations at KSC. The site provides links to technical publications and other resources, and allows data to be downloaded for further investigation.

An addition to the data archive application allows for three major improvements: display of the lightning protection ring areas pertaining to a user, the ability to play back lightning strikes on a shorter time period than one hour so a more precise assessment could be done, and the ability to convert Degree Minute Second (DMS) location information into Decimal Degree (DD) location information so the data could be exported and used in other calculations.

For the protection ring information, using Google Maps API calls — and utilizing previously developed code — the software uses asynchronous calls and Javascript to determine who the user is, where they are located (default building in Employee Information service), and in what protection ring they are located. Once determined, the default building would show up zoomed to a default level and be shown on the map. Also, the ability to find any other location and determine that protection ring (in case the user needed to go to another location) is available.

For the lightning strikes, added code allows the selection to change to a different time interval (1 hour, 10 minute, 1 minute) and then retrieve the data for that new timeframe and display it on the map. Also, the cycle information (used during playback) would show the number of strikes in the selected time interval. It would show six additional time intervals from the starting time, and would cycle and show lightning strikes for the new time interval.

This work was done by John Merrick, Philip Gemmer, Aldwin Ebuen, Stephan Whytsell, Eric Lockshine, Randall Tomes, Daniel Strohschein, and James Morrison of Abacus Technology Corporation for Kennedy Space Center. NASA is seeking partners to further develop this technology through joint cooperative research and development.
