RAIN-Global is the next-generation, 3D global, fully interactive upgrade to RAIN, a web interface that displays recent 7-day animations of precipitation rates and accumulations from IMERG-Late data, as well as cloudiness from geosynchronous IR data. Animations are updated daily for the 7-day period ending on the prior day and are available for the past 30 days.

New features include:
* Use your mouse or trackpad to adjust the camera position and zoom level at any location on Earth dynamically while animations are playing.
* Set the camera to orbit the Earth and visualize fully animated global precipitation data from an orbital perspective.
* Use the controls to "Fly To" one of 13 regions or over 200 countries and capital cities.
* Examine 7-day surface precipitation accumulation contours at 50-mm increments.
* Adjust the appearance of the globe by toggling country borders, country/city labels, and legend.
* Select performance characteristics (animation and renderer resolution and frame rate) to either enhance visual clarity or boost performance on older hardware/software.
* Get auto-generated performance-enhancing tips.

RAIN-Global can be used to explore IMERG precipitation data for recent extreme weather events at a specific date and location of interest. It is also ideal for education and outreach purposes to illustrate the value of satellite-based estimations of precipitation. RAIN-Global runs on a variety of hardware/software setups, but runs best on modern hardware and in Chrome, Safari, or Edge browsers (compatibility in Firefox is limited).

RAIN is a web interface that serves 7-day animations of precipitation rates and accumulations from IMERG data, as well as cloudiness from geosynchronously observed IR data, for several regions on Earth.

The GPM Near Real Time Viewer enables the visualization of various variables within Level 1 GMI; Level 2 GPM Profiling Algorithm (GPROF), Dual-Frequency Precipitation Radar (DPR), and Combined (CMB); and Level 3 IMERG Half Hour products. It animates the progress of the GPM Core satellite over the Earth‘s surface in virtual real time and will continue to animate as data areacquired for as long as the browser window is open. Between 15 and 30 minutes of data are visible at any given time. Twenty-four hours of files are available at any given time, and the interface enables efficient switching between time intervals within that day of data.

The STORM Event Viewer combines DPR and GMI data to provide both surface and 3D precipitation rate values. In the STORM Event Viewer, GMI maintains the same precipitation rate color scheme used in STORM VG, but DPR is given a different color scale to contrast the vertical values with the surface values. Because it can be difficult given all of the data points to assess verticality within storms, Event Viewer gives users the ability to change the color scheme for DPR from precipitation-based to altitude-based, highlighting deep convection and "hot towers" in tropical systems.

Orbit Viewer THOR is a tool for displaying the standard data products of the Global Precipitation Measurement (GPM) mission and Tropical Rainfall Measuring Mission (TRMM). THOR stands for the Tool for High-resolution Observation Review. THOR displays GPM and TRMM products on a map of the Earth when possible, and otherwise, as 2D plots or text output. Since 1997, the Precipitation Processing System (PPS) at NASA Goddard has developed and distributed many versions of Orbit Viewer THOR.

The Overflight Finder gives unregistered users the ability to determine when a platform flew over a location/region within a certain time frame.

The Satellite-Satellite Coincidence Finder gives unregistered users the ability to find when two satellites flew over the same region within a certain tolerance of minutes.

The purpose of the Science Algorithm Input/Output Toolkit (TKIO) is twofold. First, the Toolkit provides a set of commonly used routines and constants for algorithm developers and researchers. These commonly used items have been placed in the Science Algorithm Input/Output Toolkit to reduce the amount of parallel code development. By taking care of low-level details, the Precipitation Processing System (PPS) TKIO can greatly simplify the input/output (I/O) code that algorithm developers and researchers need to write.
