1. 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.


  1. 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.

  1. 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.

  1. 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).

  1. 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.
