Multisatellite observed responses of precipitation and its extremes to interannual climate variability. Hydrometeor, 15, — Donner et al The uniform spatial grid of this dataset lends itself to comparison with climate models, as long as care is taken to put the data on comparable grids. As well, there were some battery issues. Input Data satellite microwave and IR; gauge for calibration. There are some potentially spurious features in the temporal record.

Different IR datasets are used before 6 Feb and from 7 Feb onward. C6 dissertation, University of Washington. The frequency, intensity, and diurnal cycle of precipitation in surface and satellite observations over low-and mid-latitudes.
These are documented here: Input Data satellite microwave and IR; gauge for calibration. TRMM ran out of fuel in mid and began a slow descent. Journal b342 Geophysical Research Chen, C. LambrigtsenOn the quantification of oceanic rainfall using spaceborne sensors, J. Then, these indirect measurements along with direct gauge measurements over land are used as an input to a complex algorithm that produces estimates of surface rain rate on a regular grid in time and space.
The Climate Data Guide has an overview of these and many more precipitation datasets here. Particularly early in the TMPA record, there were relatively few microwave satellites.
TRMM 3B42 daily merged rainfall (research version)
The timeline for this shift is still under discussion. Timestep Sub-daily Daily Monthly.
Another issue is that, as a legacy product, shifts in input data, particularly sensor failures, might make continuation of 3B42 problematic within a short timeframe. Data G6 Made Simple: This is equally true for all runs, including the Final.

The point of handing out the data at fine scales with large uncertainty is that the user has the freedom to create averages in ways that best correspond to the problem at hand.
TRMM 3-hourly rain rate centered at 18Z. The mission uses 5 instruments: Initial testing showed that the revisions eliminated the unrepresentatively low bias in ocean values for that were related to how we treated an early version of Trjm precipitation in Version 6.
See tmrm figure here for an updated figure with version 7 data the most recent. Interpreting Rainfall Estimates as a Function of Rain Rate If you plot observed versus satellite precipitation grid values at the full 0.

Some corrections have been made to account for the changes in satellites used to generate this dataset over time. TRMM 3-hourly rain rate centered at 12Z. As discussed below, up through September calibration to TCI was computed on a month-to-month basis.

Advances in Atmospheric Sciences, 29, Dai, A. Shea A 3-hourly snapshot for August 7, 15Z. However, recent work shows some promise of getting a handle on error estimation, for example using the work by Maggioni and collaborators: Global Precipitation Climatology Project.

Version 7 Updates The TRMM data system was designed to tfmm episodic, complete reprocessings of the TRMM products to take advantage of ongoing research to improve the various scientific algorithms. This release incorporated several important changes as part of the upgrade to Version Often, the default interpolation in an analysis software package is bilinear interpolation e.
