Spatial resolution: 0.25° x 0.25°
Temporal resolution: 3 hours
Documentations: Detailed documentation and programming examples
Data Access: FTP download the original binary data files each containing precipitation, error, and source
FTP download binary data files each containing precipitation only
Data Outages: List of all the missing TMPA-RT files
TMPA-RT is an experimental product. It is produced quasi-operationally on a best-effort basis at TSDIS, with on-going scientific development by a research team in the GSFC Laboratory for Atmospheres. As such, users are encouraged to report their experiences with the data, and they should expect episodic upgrades or outages as the system develops.
