GPM Ka Outage - Current Unavailability of Ka and DPR Data Products

At 07:56:59GMT (3:56:59AM EDT) on April 22, 2020 both units on the Dual Precipitation Radar reset from Observation Mode to Standby Mode. The recovery process is ongoing for the Ka radar and we expect production of all radar products to resume normal operations soon. GMI operations and data products continue to be nominal during this time. PPS Production: PPS has put all radar and downstream product distribution on hold. Once products are released users should expect to see some partial and/or fully empty radar products. PPS will provide a complete listing of the anomaly orbits once we have all

DPR Ka Radar Data Acquisition has been Restored

Following a reset of the DPR to Standby Mode that occurred on April 22, 2020, the DPR Ka radar data acquisition has been restored. PPS is releasing the DPR and downstream data for distribution from April 22, 2020 - April 30, 2020. There are continuing short data outages for the radar that are being investigated and corrective measures are scheduled to be applied on May 14, 2020. PPS will be releasing May 2020 data in stages with an expected return to normal data availability soon after the corrective measures are applied. For Level-1 and Level-2 products, users should check the dataQuality

IMERG User Survey

The IMERG Algorithm Development Team is currently developing the next version of IMERG, V07. To help us prioritize our efforts, we have created a survey for users to identify aspects of IMERG that they consider important. Your responses will help us decide how we should focus our development effort for V07 and beyond. We deeply appreciate your responses. The survey is located at https://forms.gle/hgSMBXx7a2ScWpRSA This survey should take no more than 5 to 10 minutes. It is open through Monday, June 15.

Effective 18 June 2020 the end of GPM NRT FTP availability

At 11:00 UTC on 18 June 2020, FTP access to jsimpson will no longer be possible. The stoppage was originally scheduled for 1 June 2020 but due to the impacts of the CoVid19 pandemic, the end of FTP was delayed. Effective 11:00 UTC 18 June 2020, both jsimpson.pps.eosdis.nasa.gov and jsimpsonftps.eosdis.nasa.gov will provide FTPS access to GPM NRT data. FTPS will be the main, 24hr/7day retrieval protocol for getting GPM NRT data from PPS. Remember PPS implements explicit FTPS, FTPS retrieval will require your system administrators to open ports 64000-65000. You can find examples of using curl and wget for FTPS access to data on jsimpson in /NRTPUB/documentation/FTP-FTPS-Transition.pdf

NASA Worldview Example
Friday, June 19, 2020
What is NASA Worldview? This tool from NASA's Earth Observing System Data and Information System ( EOSDIS) provides the capability to interactively browse global, full-resolution satellite imagery and then download the underlying data, including data from the Global Precipitation Measurement Missions. Many of the 600+ available products are updated within three hours of observation, essentially showing the entire Earth as it looks "right now". This supports time-critical application areas such as wildfire management, air quality measurements, and flood monitoring. Arctic and Antarctic views of

IMERG: Integrated Multi-satellitE Retrievals for GPM

IMERG Early Run Example January 24th, 2020
Wednesday, February 26, 2020
NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) algorithm combines information from the GPM satellite constellation to estimate precipitation over the majority of the Earth's surface. IMERG is particularly valuable over areas of Earth's surface that lack ground-based precipitation-measuring instruments, including oceans and remote areas. IMERG fuses precipitation estimates collected during the TRMM satellite’s operation (2000 - 2015) with recent precipitation estimates collected by the GPM mission (2014 - present) creating a continuous precipitation dataset spanning over two decades. This extended record enables scientists to compare past and present precipitation trends, enabling more accurate climate and weather models and a better understanding of Earth’s water cycle and rainfall and snowfall patterns. IMERG also enables a wide range of applications to help communities around the world make informed decisions for disasters, disease, resource management, energy production, food security, and more.
