RAIN-Global 2 is a major upgrade to RAIN-Global 1 and addresses user-requested feedback, including:
* Select 3-day, 7-day, 10-day, or 14-day animations.
* Choose one of three graphics quality options: Basic, Medium, or High.
* View the diurnal cycle with an animated day/night base map.
* View liquid and frozen precipitation rates side-by-side.
* Toggle layers on/off (liquid/frozen rates, accumulations, clouds, phase).
* View probability of liquid precipitation.
* Change the color map for each data layer.
* Adjust accumulation min./max. values from 25-800 mm.
* Adjust animation speed from 0.50-1.25x.
* Time seek from daily to half-hourly intervals.

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.

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.
