GPM Core Observatory

Thumbnail
Friday, March 27, 2020
The Global Precipitation Measurement (GPM) Core Observatory satellite operates in low Earth orbit, carrying two instruments for measuring Earth's precipitation and serving as a calibration standard for other members of the GPM satellite constellation. The satellite was developed and tested in-house at NASA Goddard Space Flight Center and launched from Tanegashima Space Center, Japan, on February 27th, 2014. The GPM Core Observatory orbits Earth at an inclination of 65 degrees, which enables it to cut across the orbits of other microwave radiometers and sample the latitudes where nearly all precipitation occurs. A non-sun-synchronous orbit that takes it around Earth roughly 16 times per day allows it to sample precipitation at different times of the day. Data is transmitted continuously to ground systems on Earth by the Tracking and Data Relay Satellite (TDRS) communications network.

Drought and the Australia Wildfire Season

IMERG rainfall totals from Australia in November 2019
Thursday, March 12, 2020
Droughts and dry, arid conditions are naturally occurring phenomena in Australia. Such an environment is conducive to wild fires, which are started mainly by lightning and can occur throughout the year, but typically emerge between October and April and are most prevalent during the Southern Hemisphere summer; they are part of the seasonal cycle in Australia. However, some years are worse than others, and the 2019-2020 wild fire season was especially bad. It has been estimated that upwards of 46 million acres were burned, or roughly the size of the entire state of Washington. In terms of area...

File Naming Convention for Precipitation Products For the Global Precipitation Mission Measurement

Date Last Updated
October 10th, 2017
Document Description

This document describes the file naming conventions that will be used to name data products produced by the Precipitation Processing System (PPS) for the Global Precipitation Measurement (GPM) Mission. These file naming conventions are also intended to apply to files produced or reprocessed from the Tropical Rainfall Measuring Mission (TRMM) satellite during the period of GPM operations.
