Using GPM IMERG Precipitation Products and Services at the NASA Goddard Earth Sciences Data and Information Services Center to Monitor and Study MJO Events

One of the flagship products from the new Global Precipitation Measurement (GPM) mission is the Integrated Multi-Satellite Retrieval for GPM (IMERG) dataset. The IMERG algorithm merges satellite microwave, infrared, and ground-based gauge precipitation data to create precipitation estimates for the tropical- and mid-latitudes. The IMERG dataset provides precipitation data between 60°S and 60°N with a tenth of a degree horizontal resolution every thirty minutes with a latency of four hours. The NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) hosts and distributes IMERG data within the NASA Earth Observation System Data Information System (EOSDIS).

The high temporal and spatial resolutions of the IMERG dataset place it in a unique position to analyze the meso and synoptic scale structures of the MJO. This poster will demonstrate how scientists and forecasters can use the GES DISC OPeNDAP and interactive visualization and analysis tool Giovanni services to quickly and easily analyze past and current MJO events. These capabilities will be demonstrated through analysis of the MJO events that occurred during June and July 2015.
