Science Team On-Line Request Module (STORM) is a publicly available web-based data access interface for the Global Precipitation Measurement (GPM) Mission's Precipitation Processing System (PPS). PPS is one of the first measurement-based processing systems approved by NASA Headquarters; it employs a recognized scientific measurement and provides continuity between data from previous and future satellite missions. PPS generates precipitation data using radar and microwave measurements from the Precipitation Measurement Missions (PMM), including GPM and the Tropical Rainfall Measuring Mission (TRMM). The purpose of STORM is to provide the science community, students, and the public with an opportunity to learn about GPM data, search for data, order custom subsets, and subscribe to receive subset products produced in the future.


Data Source Instructions

Data Access is the core of STORM that allows users to access PPS data in various ways.

  • Browse Archive is a link to the PPS public online archive. Users can search for data by drilling down through the directories.
  • Search Archive/Order is the interface to use when searching for data based on various parameters, setting up subscriptions, and ordering custom subsets.
  • Track Order Status allows you to check on the status of your orders and subscriptions, and to cancel subscriptions.
  • Satellite-Ground and Satellite-Satellite Coincidence allow you to explore the coincidence interfaces without requiring registration or involving data download.
