The image service provides global coverage with a temporal span from 06/01/2000 0:00 UTC to present at 1-day intervals.</span></p><p><span>IMERG is an algorithm that estimates precipitation rate from multiple passive microwave sensors in the GPM constellation, the GPM Dual-Frequency Radar, and infrared (IR) sensors mounted on geostationary satellites. Currently, the near-real-time Early estimates have no concluding calibration. Briefly describing the Early Run, the input precipitation estimates computed from the various satellite passive microwave sensors are intercalibrated to the Combined Radar-Radiometer Algorithm (CORRA) product (because it is presumed to be the best snapshot Tropical Rainfall Measuring Mission (TRMM)/GPM estimate after adjustment to the monthly Global Precipitation Climatology Project Satellite-Gauge (GPCP SG)), then "forward morphed" and combined with microwave precipitation-calibrated geo-IR fields to provide half-hourly precipitation estimates on a 0.1°x0.1° (roughly 10x10 km) grid over the globe. Precipitation phase is computed using analyses of surface temperature, humidity, and pressure.</span></p><p><span style='font-weight:bold;'>Dataset at a Glance</span></p><p><span>Shortname: GPM_3IMERGDL</span></p><p><span>DOI: 10.5067/GPM/IMERGDL/DAY/07</span></p><p><span>Version: 07</span></p><p><span>Coverage: -180.0,-90.0,180.0,90.0</span></p><p><span>Temporal Coverage: Subset is from 2025-07-01 to Present</span></p><p><span style='font-weight:bold;'>Data Resolution</span></p><p><span>Spatial: 0.1 ° x 0.1 °</span></p><p><span>Temporal: 1 day</span></p><p><span style='font-weight:bold;'>Symbology</span></p><p><span>The default symbology in the Map Viewer may be changed to accommodate other color schemes using the settings in the Image Display panel from the layer settings menu. NoData values, and values less than 0.03 mm/hr (the current threshold value for the IMERG algorithm) have been removed. Ensure that pop-ups are enabled to view pixel values (select Modify Map first).</span></p><p><span style='font-weight:bold;'>Temporal Coverage</span></p><p><span>The source dataset is in UTC time but the service is displayed in the Map Viewer in local time. The data is available in daily intervals, and the map visualization may be modified by opening the Time Slider Settings menu from the icon on the time slider bar. The total temporal coverage may be limited to the desired range and the time interval may also be changed. The options in the time interval units are based on the total time range input, so a shorter time range will enable shorter time units to be selected from the time interval drop-down menu. If the time settings are set to more than 30-minute intervals, the first time slice in the time interval is visible.<br /><br /><b>Suggested Use:</b><br /><br /></span><a href='https://daac.gsfc.nasa.gov/information/howto?keywords=GIS&title=How%20to%20access%20the%20GES%20DISC%20IMERG%20ArcGIS%20Image%20Service%20using%20the%20ArcGIS%20Enterprise%20Map%20Viewer' rel='nofollow ugc' target='_blank'>Access GES DISC How-To's</a><span> for additional portal option information.</span></p><p><b>Data Download:</b></p><p><a href='https://gpm1.gesdisc.eosdis.nasa.gov/data/GPM_L3/GPM_3IMERGDL.07/2025/07/' rel='nofollow ugc' target='_blank'>https://gpm1.gesdisc.eosdis.nasa.gov/data/GPM_L3/GPM_3IMERGDL.07/2025/07/</a></p></div> |
