NUMBER 228 DATE: 07/15/02

Sector Processing Center (SPC):

During May, EUM, JMA, CSU, MSC and NOA processed more than 91% of A data into B1/B2 data.

Normal operations for May were reported by EUM, JMA, CSU, MSC and NOA.

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 May 02 from NOAA-16 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for March 02 for METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10 were shipped to the GPC. Processing of the normalization for the "water vapor" channels is delayed to accommodate changes between NOAA-14 and NOAA-16 HIRS data.

AC data for GMS are received on CD-rom; all other AC data are received and the BC data are sent 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, including the B2 data from NOA. All data (except DX) from the GPC are delivered by ftp to NOAA/NCDC and to NASA Langley.

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 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 now 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. We have also processed the data for August 81 through June 83.

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

All data products are currently delivered by ftp to the ICA and NASA Langley (except for DX data). The GPC has completed copying of its entire data holdings onto new, much denser tape media.

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 December 99 and climatology results based on the period July 83 through December 99. 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 and NOAA-16 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. NOAA successfully launched NOAA-17 into a morning polar orbit on 24 June 02; the equator crossing time for this and subsequent morning orbiters will be later, about 1000 local time. The problems with AMSR-E on NASA's Aqua were corrected. ADEOS-II is scheduled for launch in November 02.
