Map Guide to Analysis of Current Conditions
All maps are derived from the Experimental Near-Real-Time TRMM Multi-Satellite Precipitation Analysis (TMPA or 3B42RT). A brief description is here and a more detailed documentation is also available. The daily climatology was derived from the 3-hourly TRMM and Others Rainfall Estimate (3B42 V6) between
1998 and 2005.
Note: 3B42RT 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.
At present, all maps are updated daily after 0 Z.
Map descriptions:
- Accumulated Rainfall: Rainfall total during the specified period. Unit: mm
- Rainfall Anomaly: rainfall total - daily climatology. Unit: mm. Note: Does not apply to 3-hourly and daily maps.
- Percent of Normal: ((rainfall total)/(daily climatology))x100%. Unitless. Note: Does not apply to 3-hourly and daily maps.
