Large-Scale Precipitation Tracking: Data Access

Summary

Example Python code for IMERG LPT data: html Jupyter Notebook.

Kerns and Chen (2020) Data
IMERG V6
CMORPH
ERA5

This page provides access to the LPT system database used by Kerns and Chen (2020, JGR Atmospheres) (pdf). These data are for June 1998 - June 2018. NASA 3B42/TMPA data are used.

In the near future, I plan to add:

An extended database covering more years of TMPA.
An LPT database using CMORPH and IMERG.
A near real-time site using CMORPH and IMERG real time products.
Interactive map display

For more information and/or potential collaborations, feel free to contact me at bkerns AT uw.edu. I can also be reached via my Twitter handle @brandonwkerns.
