ISCCP PROJECT STATUS REPORT
NUMBER 290 DATE: 09/11/07
Sector Processing Center (SPC):
During July, NOA, JMA CSU and MSC processed greater than 99% of A data into B1/B2 data. CSU eliminated the backlog of reports: they processed 100, 100, 99.6, 99.6 and 100% of A data into B1/B2 data for February, March, April, May and June, respectively.
Normal operations for July were reported by NOA, JMA, CSU and MSC. No reports have been received from EUM for October 06 through July 07.
Satellite Calibration Center (SCC):
AC data were received for July 07 from MTSAT-1R, FY-2C, GOES-11, GOES-12, METEOSAT-7, METEOSAT-8 and NOAA-18. BC data are complete through May 07 for MTSAT-1R, FY-2C, GOES-11, GOES-12, METEOSAT-7 and METEOSAT-8.
All AC data are now received via Internet.
All BC reports now include normalization for the visible, standard infrared and “split-window” infrared channels (except for METEOSAT-7 and GOES-12 which do not have a split-window channel).
Global Processing Center (GPC):
The GPC continued to receive B2 data, BC data and correlative data in a routine manner by Internet. All data products from the GPC are delivered by ftp to NOAA/NCDC and to NASA Langley.
Deliveries of B2 data from NOAA-18 are current. Production of NOAA-18 (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Deliveries of B2 data from NOAA-17 are current. Production of NOAA-17 (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Deliveries of B2 data from GOES-11 are current. Production of GOES-11 (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Deliveries of B2 data from GOES-12 are current. Production of GOES-12 (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Deliveries of B2 data from METEOSAT-5 (at 63°E) are complete through January 07, the last data. Production of METEOSAT-5 (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Deliveries of B2 data from METEOSAT-7 (at 55°E) are current.
Deliveries of B2 data from METEOSAT-8 are current. Production of NOAA-18 (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Deliveries of B2 data from MTSAT-1R are current. Production of MTSAT-1R (preliminary) B3 is complete through December 06. Final B3 data have been produced through December 06.
Delivery of B2 data from FY-2C has been received covering the period from November 05 through April 07, eliminating the backlog. Delivery of current data by ftp has resumed; the GPC is now inventorying the whole collection.
Deliveries of TOVS correlative data are current. TOVS processing is complete through December 06.
Deliveries of snow/ice correlative data are current. SI processing is complete through December 06.
DX/D1/D2 data processing is complete through June 06 (without FY-2C). Processing is nearly complete for the remainder of 06; investigation of the VIS calibration for MET-8 is still underway.
The online bibliography of papers based on ISCCP datasets has been updated through December 06; over 1300 ISCCP-related papers have been published.
The cloud climatology plots and browse data, the BT and D2 holdings on the ftp site, the radiance calibration and product version number tables have all been updated through June 06.
New “cluster” analysis results for an extended low-latitude regime and the midlatitude cyclone regimes have been added to the website.

ISCCP Central Archives (ICA):
The ICA at NOAA NCDC continued to receive B1 data from NOA, JMA, EUM, CSU, MSC and CMA and B3 and DX/D1/D2 data from the GPC in a routine manner.
5th ANNUAL WGDMA MEETING
The 5th annual meeting of the Working Group on Data Management and Analysis was held 5-7 September at The City College of New York. This is the meeting for the data processing centers comprising all of the GRP global data projects, including ISCCP. Meeting goals were to continue work in preparation for a coordinated re-processing of all the products later this decade, to develop criteria for selecting common ancillary datasets and to design common data formats. Specific topics discussed and decisions made with regard to ISCCP were as follows: (1) the primary improvements being investigated for ISCCP include revised calibration using modern instruments now in orbit (new funding has been approved), improved polar cloud detection and reduction of the satellite-view-dependence in the retrievals, (2) the most important systematic problems with the TOVS atmospheric temperature/humidity dataset are lack of diurnal resolution and spurious interannual variations, and (3) if the switch from B3 to B1U radiances is approved, then the ISCCP products can be reported at a finer spatial resolution (possibly 50 km) and in a format in common with all of the other products. Assuming renewal of funding is approved, these revisions to the ISCCP analysis software should be ready to begin re-processing early in 09.
SATELLITE HEALTH
The health of GOES-11, GOES-12, MTSAT-1R, METEOSAT-7, METEOSAT-8, FY-2C, NOAA-17 and NOAA-18 remained good. METEOSAT-5, METEOSAT-6, METEOSAT-9, GOES-13 and MTSAT-2 are in stand-by mode. GOES-10 has been moved to 60 degrees west longitude to provide better coverage of South America; Brazil has indicated plans to provide B1/B2 data from this satellite for ISCCP.
