Presentation Transcript

  1. PEHRPP Applications Working Group Summary, Recommendations, and Future Directions Chairs: Val Anatharaj and Matt Sapiano Bob Adler, Phil Arkin, Ralph Ferraro, Matt Garcia, Kosta Georgakakos, Prasatha Hapuarachchi, Christa Peters-Lidard, Joe Turk PHERPP Applications Working Group (5 Dec 2007)

  2. Topics of discussion • Types of applications, classes of users • Uncertainty estimates and ancillary data • Data availability, continuity, and succession • Mathematical and technical frameworks for adding value to products – blending, merging, downscaling PHERPP Applications Working Group (5 Dec 2007)

  3. Types of applications • Hydrology (ex. flood forecasting) • Global hazards • NWP modelers (for validation and assimilation) • Operational forecasters • Short-term climate (extremes and variability) • Agriculture and food security • Water resources and quality • Public health • Economists • Transportation and military operations • Others PHERPP Applications Working Group (5 Dec 2007)

  4. Recommendations (1) • 1. Product developers should be encouraged to formulate and produce error estimates for the products • 1a. By engaging end users, IPWG should investigate the forms of error required for applications. • 1b. Since full error estimates will take time to obtain, developers should be encouraged to make other information available such as the main source of data (i.e. SSM/I F13 GPROF V6) and the latency of MW data (time since last MW overpass). PHERPP Applications Working Group (5 Dec 2007)

  5. Recommendation (2) • 2. PEHRPP/IPWG should make satellite organizations aware of the fact that MW data are useful for a broad range of applications and that these applications would benefit from more data, faster data delivery and the maintenance of all existing data-streams. • 3. Product developers should be encouraged to pursue other assimilation and/or downscaling methodologies which exploit all available information (satellites, NWP, gauges, lightning estimates), particularly those which are optimized for specific applications • 3a. PEHRPP/IPWG should facilitate communication between Algorithm developers (including base product providers) and the end users. PHERPP Applications Working Group (5 Dec 2007)

  6. Future directions for PEHRPP • More work is needed to understand the characteristics and errors of the HRPPs at sub-daily timescales and at very high resolution. • A study of the impact of the HRPPs at the application level is required to highlight the utility of these data to policy-makers. • PEHRPP/IPWG should implement a data distribution/imaging interface (such as the Giovanni interface) for end users • PEHRPP needs to advertise the existence of the HRPPs to end users, including non-traditional users.
