NOAA Direct Broadcast Data Initiative to Meet NWP Latency Requirements

NOAA WP-13

Filename.ppt 2

Responsive to CGMS Action

● Action 40.18: CGMS Agencies to support fast delivery initiatives using direct broadcast with extensions wherever possible (e.g., IASI, METOP-B, NPP), including on future polar orbiting satellites.

Any latency requests less than total system latency for JPSS (103 minutes) are captured as objective latencies for each respective product3

• NOAA operational Line Offices have provided true latency values for their respective critical products (focusing on the near-real time requirements)

Community Supported Processing Package (CSPP) demonstrates the value of 15- 30 minute latency for nowcasting and regional forecast model applications by establishing a network of direct readout stations - includes METOP and All Polar Orbiting Satellites with DB

Scope

● Gap mitigation for NPP/JPSS-1 or JPSS-1/JPSS-2 by securing all existing satellite sounder data with direct broadcast with significantly improved latency – goal of 15 minutes, threshold of 30.

● Sounder data are relayed back to NSOF and CIMSS (UW) for distribution to NCEP Central Operations.

● Existing NOAA priority sites: WI, AK, HI

● Expand to: Guam, Miami, Puerto Rico, and Suitland. >> connect to EUMETSAT sites

● Access to Japan site (JMA)

● Sounder data from all METOP, POES, JPSS.

● Add GCOM capabilities

● Potential to include Russian Meteor-M and Chinese FY-3 series.

● Additional benefits – local use of DB by local NWS office and other customers.

Execution

● Kickoff meeting in April 2013

● Identified POC/hosts in Miami and PR

● CIMSS/UW - acquire and install Miami and PR antennas

● OSPO – contract to install Monterrey, with options for remaining antennas.

● Communication analysis by OSD confirmed all sites with exception of Guam will not need additional comm support.

● Use CSPP and include call home feature for data exploitation from external sites.

CSPP Users 23 January 2013

More than 250 people have registered to downloaded some part of the CSPP suite of products representing 33 different countries, including all 7 continents.

• New EARS Suomi NPP Services to start during 2012.

• The contributions from the:• Station Partners• NWP-SAF • CSPP Team• Users

are essential for the successful implementation of the new services and are highly appreciated!

Recommendations

● Work with WMO to fully engage NOAA Direct Readout Initiative

● NOAA welcomes the participation of other CGMS agencies. We would like to include FY3 and Russian satellites and would encourage open access to level 0 and level 1 processing code to convert satellite data packets to calibrated sensor observations.
