NUMBER 230 DATE: 09/06/02

Sector Processing Center (SPC):

During July, EUM, JMA, CSU, MSC and NOA processed more than 97% of A data into B1/B2 data.

Normal operations for July were reported by EUM, JMA, CSU, MSC and NOA. NOA delivered the first B2 data from NOAA-17 to the GPC.

CSU is still supplying the AC data for GOES-8 because the SCC has not accepted the revised format from MSC.

Satellite Calibration Center (SCC):

AC data were received for July 02 from NOAA-16 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for May 02 for METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10 were shipped to the GPC. The delayed processing of the normalization for the "water vapor" channels to NOAA-16 HIRS has commenced and is complete through November 01.

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 METEOSAT which does not have a split-window channel), and the "water vapor" channels.

Global Processing Center (GPC):

The GPC continued to receive B2 data, BC data and correlative data in a routine manner. All of these data are now received by Internet. All data products (except DX) from the GPC are delivered by ftp to NOAA/NCDC and to NASA Langley. All delivery backlogs have now been eliminated.

Deliveries of B2 data from NOAA-16 are current. A prototype formatter code, which neglects the 1.6 micron channel data, has been written and all of the NOAA-16 B2 data processed into a preliminary form of B3 data to allow for calibration analysis.

Deliveries of B2 data from NOAA-17 are current.

Deliveries of B2 data from GOES-8 are current. Production of GOES-8 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from GOES-10 are current. Production of GOES-10 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from METEOSAT-5 (at 63E) are current. Production of METEOSAT-5 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from METEOSAT-7 are current. Production of METEOSAT-7 (preliminary) B3 data is compete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from GMS-5 are current. Production of GMS-5 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of TOVS correlative data are current. TOVS processing is complete through September 01. A format change in TOVS occurred in October 01, so the processing software will have to be modified.

Deliveries of snow/ice correlative data are current. Production of the snow/ice dataset is complete through September 01.

DX/D1/D2 data processing is complete through September 01. An investigation to identify all small processing/calibration errors continues.

Two CDs of D2 data are now available from NASA Langley, covering 83-88 and 89-93. A new CD covering 94-98 will be released within the next month or two.

The entire D2 dataset is now available on the ISCCP Web site. Browse data now available on the Web site are monthly mean data for July 83 through September 01 and climatology results based on the period July 83 through September 01. The radiance calibration tables have been updated through September 01. All of the documentation is now being reviewed and brought up to date.

ISCCP Central Archive (ICA):

The ICA continued to receive B1 data from NOA, MSC, EUM, CSU and JMA and B3 and D data from the GPC in a routine manner.

The health of GOES-8, GOES-10, GMS-5, METEOSAT-5, METEOSAT-7, NOAA-16 and NOAA-17 remained good. METEOSAT-6, GOES-11 and GOES-12 are in stand-by mode. NOAA has agreed to move GOES-9 westward to provide supplementary coverage for GMS-5 until MTSAT-1R can be launched next year. MSG-1 was successfully launched on 28 August 02 and will become operational in mid-03. METEOSAT-7 (and METEOSAT-5) operations will continue through at least 2005.

Stage B3: July 83 - September 01 (18.2 years)

Stage TV: July 83 - September 01 (18.2 years)

Stage SI: July 83 - September 01 (18.2 years)

Stage D: July 83 - September 01 (18.2 years)
