An Analysis and Example of Use of the GPM Gridded Text Products

This poster provides the design, content and purpose of the
Global Precipitation Measurement (GPM) gridded text
products. Gridded text products at the same time and space resolution are
available from the start of the TRMM period in January 1998 through the
current GPM data collection period. The poster provides an example of the
use of this data product by examining the structure of the Indian monsoon as
well as examining the monsoon during El Nino and La Nina periods. It will
also look at diurnal precipitation during the Indian monsoon season. As
part of the examination of the Indian monsoon using the gridded text
product, the poster demonstrates the ease of integration with other data.
In this case, Sea Surface Temperature (SST) data that is relevant to the Indian monsoon is examined
side-by-side with the precipitation data. It further demonstrates the ease
of aggregating the daily gridded data across many years while still
retaining the hourly structure that enables diurnal studies. The GPM
gridded text product is currently the only level 3 GPM product which can
be aggregated in this way. The representation of data in ASCII format
allows potential users to concentrate on the scientific analysis rather
than the physical format of the data. In summary, the poster provides an
overview that uses examples to demonstrate the efficacy of this unique GPM
data product.
