TRMM V6 Reprocessing Trending Results


Privacy, Security, Notices


TSDIS started reprocessing all TRMM data as of  April 1, 2004 with the V6 algorithms. The earliest data date is Dec. 8, 1997, however not all instruments were operational at that time. TSDIS performs reprocessing at an accelerated rate, sometimes producing 15 data days per day. 

The trending software is run on each orbit of data producing ASCII files that contain the sum, sum of squares and count information of each variable along with other bookeeping information. These trend files are then used to make the various graphs shown below.

The ASCII trend files can be downloaded from the V6 RP Trend Data Files Page

Time Series Plots and Histogram
Below are the trending graphs organized by algorithm.

blue bullet graphic Time series plots display the mean and standard deviation of a variable per day.
The average of the daily means is listed on the x-axis.

blue bullet graphic Histogram plots  The vertical lines in the graphs denote the means the distributions. The base data for the histograms are the means computed from every orbit in the trend files.  Histograms are presented in terms of  % of data.
