NOAA’s Near-, Mid-, and Long-Term Goals
NOAA NEAR-TERM GOALS (2005-2010)
-
Data Processing/Algorithm Implementation:
-
NOAA should leverage off of NASA’s effort on the Precipitation Processing System to develop a parallel joint NOAA-NASA precipitation processing system to be run at NOAA in near real time.
-
Develop a prototype global quantitative precipitation estimation (QPE) (merged satellite, radar and gauge) that can serve as a “day-1” analysis system when data from GPM become available. Utilize measurements from new networks such as NERON.
-
-
R&D:
-
Develop advanced multisensor retrieval algorithms, with emphasis on cold-season and orographic precipitation.
-
Provide accurate estimates of magnitude of global oceanic precipitation.
-
-
Instrumentation:
-
Perform GPM risk reduction activities by utilizing TRMM measurements.
-
Develop advanced instrumentation to obtain accurate 3-D information
-
Utilize testbeds to improve QPE via new instrumentation. and characteristics of precipitation from ground (e.g., polarmetric radars, profilers, disdrometers, etc.).
-
-
Applications - NWP (JCSDA):
-
Improve assimilation of radiances to produce accurate global moisture and precipitation fields in data assimilation.
-
Provide accurate precipitation estimates independent of the data assimilation system for validation and calibration.
-
Provide near-real-time accurate estimates of global precipitation over land for assimilation in land data assimilation.
-
NOAA MID-TERM GOALS (2010-2015)
-
Data Processing/Algorithm Implementation:
-
Parallel/joint PPS operated through joint facility similar to JCSDA.
-
Integration of in situ data (gauge, radar, other) into regional and global analysis.
-
Collect past measurements of precipitation and satellite radiances for as long as possible and process these to give as long, accurate, consistent records as possible.
-
-
R&D:
-
Continued development of advanced retrieval algorithms to include probabilistic QPE and utilization of cloud microphysics for NWP, flash flood, and climate.
-
Establish and carry out on-going reanalyses to produce extended and consistent historical records of precipitation.
-
-
Instrumentation:
-
Continued utilizations of testbeds.
-
Continue to support new technologies and organize into networks (e.g., WSR-88D upgrade to dual-polarization).
-
Utilization of GPM measurements along with advanced retrieval techniques to define future NOAA precipitation program/mission (GPM follow-on) and Geo-MW (GOES-R series).
-
-
Applications - Climate & NWP (JCSDA):
-
Direct assimilation of precipitation estimates in NWP.
-
Improve observed and modeled accuracy of tropical precipitation and distribution of latent heat release to improve hurricane, medium-range, monthly, and seasonal forecasts.
-
Improve forecasts of precipitation globally, with a short-range focus on the United States.
-
NOAA LONG-TERM GOALS (2015+)
-
Data production continues via joint GPM facility, including international partners.
-
NOAA-wide use of unified QPE.
-
Evaluate and improve mesoscale quantitative precipitation forecasts through new models capable of incorporating cloud-scale processes.
-
NOAA operational precipitation mission established—could be POES and/ or GOES.
