TL;DR: The Tropical Rainfall Measuring Mission (TRMM) was launched on 27 November 1997, and data from all the instruments first became available approximately 30 days after the launch as mentioned in this paper, and much progress has been made in the calibration of the sensors, the improvement of the rainfall algorithms, and applications of these results to areas such as data assimilation and model initialization.

TL;DR: The behavior and various controls of diurnal variability in tropical-subtropical rainfall are investigated using tropical rainfall measuring mission (TRMM) precipitation measurements retrieved from: (1) TRMM Microwave Imager (TMI), (2) Precipitation Radar (PR), and (3) TMI/PR Combined, standard level 2 algorithms for the 1998 annual cycle as discussed by the authors.

TL;DR: The Tropical Rainfall Measuring Mission (TRMM)'s 'day-1' combined rada/radiometer algorithm uses a rainprofiling approach which gives as much importance to the measurement of the TRMM satellite's precipitation radar (PR) as their respective intrinsic ambiguities warrant, which avoids any ad hoc shortcuts that might introduce large biases in the rain estimates as mentioned in this paper.

TL;DR: The International Satellite Cloud Climatology Project (ISCCP) project as discussed by the authors conducted a pilot study initiated in late 1981 to evaluate currently available cloud analysis algorithms, which focused on the most fundamental step of any cloud algorithm, namely cloud detection.

TL;DR: In this article, the success of any passive microwave precipitation retrieval algorithm relies on the proper identification of rain areas and the elimination of surface areas that produce a signature similar to that of precipitation.
