How much it rained, with vertical detail, daily (GPM)

GPM DPR Precipitation Profile 1 Day Ascending 0.25 degree x 0.25 degree V07 (GPM_3DPR_ASC) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. Daily summaries of how much rain fell, including vertical detail showing precipitation at different heights, gridded globally and including statistics like the average and number of measurements per grid box.

How it's made. Built by accumulating instant rainfall estimates from the GPM mission's dual-frequency radar into daily grids; this is the ascending-orbit Level 3 product at about 0.25-degree resolution.

How & where you'd use it. Convenient for comparing satellite rainfall with ground and other satellite data, and for studying global precipitation patterns and storm structure.

Official description

Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07. . The Level 3 DPR products present the user with summary information over daily and monthly time periods. These gridded products are in a convenient gridded form and can be used easily in comparisons with other satellite and ground data. The Level 3 DPR algorithm accumulates instantaneous precipitation estimates from the Level 2 retrieval algorithms into grids over a day and month time span. There are two grid resolutions: 5.0 degrees and 25 kms. For each grid box, the core statistics are the number of measurements, mean, and standard deviation. Most variables are also conditioned on surface type and precipitation type with other three-dimensional fields adding the height above the ellipsoid. Unless otherwise specified, the means are conditioned on precipitation being present (rain rate > 0). For the daily product, the mean square statistic is saved rather than the standard deviation. In addition to the daily and monthly products is a simplified joint daily product that contains a subset of the fields from the full daily product.
