Outline• Review of NOAA Operational Satellites and
their importance for Hydrological Applications– Individual sensors/products
– Emerging blended products
• Future vision– Potential new products/enhancements
– GPM era/NOAA Precipitation Enterprise
8-12 April 2013 2013 NOAA Satellite Conference – College Park, MD
Satellites for Hydrological Applications
• Satellites are particularly useful where ground measurements are:– Not taken or missing
• Examples – Sparse rain gauges and data delivery failure (maybe caused by an extreme rainfall event)
– Of questionable quality• Examples – radar missing offshore rain; radar beam blockage in mountains
– Not possible• Example – Open ocean
• NESDIS provides operational satellite products of hydrological parameters for each individual satellite it operates. – GOES – visible and IR based, rapid update– POES – passive MW, 3 satellite, 4 hour global coverage
• NOAA also utilizes satellite assets from other agencies like NASA, DoD, EUMETSAT and JAXA

Blended TPW (bTPW) Producthttp://www.osdpd.noaa.gov/bTPW/index.html
• bTPW algorithm – Kidder and Jones, 2007
– Histogram matching to common reference
• The bTPW product combines all available data sources into a “seamless” product for use by the NWS forecaster
– Ocean – Satellite MW– Land – Satellite MW and GOES
Sounder; GPS Met• Most flooding events can be linked
to “atmospheric rivers” – high TPW that focus on a given location for extended period
– Connection from (sub)tropics to mid and high latitudes
• Product is useful to weather forecasters
– Timing & magnitude of moisture “surges” (NWP models might miss)
• Companion TPW Anomaly (from climatology) Product

Characterization of Precipitation Field in High Latitudes of the Northern Hemisphere for the Future Use with the GPM Mission Products for Hydrological & Climate Change Assessments
P. Groisman, D. Easterling, B. Nelson, D. Yang, V. Alexeev, et al.
• In the United States, we will secure the time series homogeneity of most national in situ networks used for the national climate change assessments;
• For the high latitudes of the Northern Hemisphere, we will update and maintain the science-quality archive of homogeneous daily precipitation time series;
• To facilitate the future fusion of GPM products with other hydrometeorological information in the high latitudes, we will generate the ‘ground truth’ regional (grid cell) precipitation and estimate the accuracy of this ‘truth’ values;
Left. Mean intense (i.e., >12.7 mm d-1) precipitation, mm×(event)-1 that comes with 1-day- and 2-day-long events over the contiguous United States.
Right. Nationwide annual precipitation intensity, I, changes over Russia.

• We will estimate light precipitation in high latitudes using gauges in combination with synoptic and surface data. Because the perspectives to secure measurements of light precipitation from space are elusive, these in situ data will complement future GPM products in high latitudes and jointly serve for hydrological applications and climate and environmental change analyses.

Analysis and Validation of GPM in LAPS Data Assimilation System
Y. F. Xie, S. Albers, S. Gutman, D. Birkenheuer, H. L. Jiang, and Z. TothGlobal Systems Division, Earth System Research Lab, NOAA/OAR
• Variational LAPS is a hotstart and multiscale data assimilation system used by 150+ users worldwide;
• With new or modified forward operators, GPM data will be tested in V-LAPS analysis and evaluated for its impact;
• For data validation, assimilated GPM data or products will be compared with Doppler radar reflectivity over selected domains and the differences will be described;
• After validation, GPM forward operators and assimilation methodologies can be used in parallel runs of global forecast systems (e.g. the Finite-volume Icosahedral Model-FIM) to evaluate the impact of GPM data in these models, particularly over the ocean.
GPM data could potentially improve LAPS cloud, rain, snow, and graupel analysis over areas without radar coverage
