Requirement:1) Weather and Water Goal –Improve water resources forecasting capabilities. 2) Climate Goal - Develop an integrated global observation & data management system for routine delivery of information, including attribution of the
state of the climate. 3) Mission Support Goal – Advancing space-based data
collection capabilities and associated platforms and systems.
Science:How do we utilize satellite measurements from the GPM-era sensors to
improve regional & global precipitation estimates for all precipitation types?
Benefit:The development of state-of-the are precipitation retrievals from satellites complements NOAA’s surface measurements and offer improved accuracy for use in weather forecasts, NWP assimilation, hydrology, etc.
3. Science Progress
During the past several years, STAR PI’s have been active participants on
NASA’s Precipitation Measurement Missions (PMM) science Team – PMM
comprises of both TRMM and GPM. Through an innovative funding
arrangement between NOAA (75%) and NASA (25%), four NOAA PI’s (2
NESDIS; 1 NWS; 1 OAR) have provided significant contributions to the
PMM team. The NESDIS lead projects are:
R. Kuligowski, PI: “Utilizing TRMM Precipitation Products in Operational
Hydrology through Multi-Satellite and Multi-Sensor Quantitative
Precipitation Estimation (QPE)”
R. Ferraro, PI: “Improved Microwave Precipitation Over Land from TRMM
through GPM Era”
Some results are presented in the figures below.
4. GPM Transition Progress
A draft Transition Plan for was developed and is under review by the NESDIS
Transition Team, which is also focusing on continuity missions such as GPS,
Ocean Wind Vectors, Solar Wind, etc. The primary R2O for GPM would be the
hand over of NASA’s Precipitation Processing System (PPS) to NESDIS for
operational delivery of GPM based products (figure below).
Additionally, it’s envisioned that through NOAA funded R&D, a consolidated
suite of NOAA precipitation products, using combined satellite, radar and rain
gauges would blossom during the GPM-era and would benefit all of NOAA
(second figure below).
Historically, STAR interacts with NASA through NASA’s competitive proposal process;
these activities are carried out through instrument “Science Teams”. Examples include: AIRS, MODIS, AMSR-E and TRMM – several algorithms being used today have STAR roots. In order to prepare for upcoming “Decadal Survey” missions, NOAA & NASA
have recently developed joint Research to Operations (R2O) teams – the degree of involvement of these teams is a function of the missions’ maturity. It is the purpose
of this poster to highlight the R2O activities related to the Global Precipitation Measurement (GPM) Mission.
2. GPM Overview
The GPM Mission is a joint venture between NASA and JAXA that builds off the
successful TRMM program. GPM’s core satellite will contain advanced sensors (GMI
and DPR) that will be capable of measuring light precipitation such as snow. The core satellite is used as the calibrator for the passive microwave sensors that will be part of
the GPM “Constellation” – a fleet of operational and research satellites that will allow for global, 3-hourly or less precipitation estimates.
Science Challenges: Advancing the state-of-the-art in precipitation retrieval, especially in cold seasons. Integrating all available measurements into seamless product for users.
Next Steps: Secure NOAA resources for increased participation in GPM to continue R&D that integrates into NOAA applications soon after GPM core launch in 2013.
Transition Path: Continued development and evolution of Transition Plan and the
NASA-NOAA R2O concept.
