NWS / SPoRT Coordination CallOctober 2010

NWA posters/presentationsScott Overpeck, Chris McKinney, and Kent Prochazka, WFO Houston/Galveston. The Coastal Gravity Wave Event of 24 April 2010. Deirdre Kann and Brian Guyer, WFO Albuquerque. The Operational Use of NASA SPoRT Imagery at NWS Albuquerque. CIRA TPW - Newest Version We will discuss the recent change to the CIRA TPW data set being provided through SPoRT which is using the MIRS data vs the current operational NESDIS version without MIRS.

The new CIRA TPW productBased on use of MIRS

Microwave Integrated Retrieval Systemhttp://mirs.nesdis.noaa.gov/

Presently from subset of satellites and has slower refresh rate vs old product

Overland priority: 1) GPS-met, 2) GOES Sounder, 3) MIRS

“Overlay” vs “Averaged” Product The overlay advantage is a more realistic

movement of moisture surges; but the final TPW product appears patchy with discontinuities at swath edges

Binomial smoother is used to lessen discontinuities from “overlay” method.

GPS-met and GOES Sounder used only over land

GPS for isolated locations use smaller circle of influence 8/3/2009

Coverage of CIRA TPW from SPoRTCIRA version, MIRS-based NESDIS version, no MIRS

8/3/2009

Max. TPW Value DifferencesCIRA TPW (w/ MIRS) NESDIS TPW (no MIRS)

8/3/2009

Areas of maximum TPW in CIRA version are lower, due to binomial

smoother, differences in data used and timing of data processing.

CIRA TPW Anomaly DifferencesCIRA TPW (w/ MIRS) NESDIS TPW (no MIRS)

8/3/2009

Smaller area of 200% of normal. Noticeable couplet of max/min in

NESDIS version compared to CIRA over Nevada.

Next Generation CIRA TPWThis is the future type of the product that is

likely to be supplied by NESDIS to the WFOs.Anticipating more details from CIRA on the

new product validation and caveatsEvaluation feedback needed from end users

due to noted differences in final product.

Next Call – November 18, 2010Main topic: GOES-R Proving Ground products

to be evaluated by SPoRT partnersLightning: A Pseudo-GLM product has been

developed by SPoRT. Evaluation of this product is needed using WES cases.

Imagery: Several groups are creating ABI proxy products. SPoRT is focusing on near-realtime products to simulate ABI. This will combine GOES and MODIS (possibly VIIRS in future) at the resolution of ABI in order to prep users for the coming GOES-R era. Evaluation in a concentrated time period is needed for those willing.
