NUMBER 215 DATE: 06/08/01

Sector Processing Center (SPC):

During April, EUM, JMA, CSU and MSC processed 98% of A data into B1/B2 data.

Normal operations for April were reported by EUM, JMA, CSU and MSC. NOA funding is now being arranged through satellite operations, so processing of B2 data has resumed. NOAA-14 B2 data for September thru December 00 were sent to the GPC.

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

Satellite Calibration Center (SCC):

AC data were received for April 01 from NOAA-14 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for February 01 for GOES-8, GOES-10, METEOSAT-5, METEOSAT-7 and GMS-5 were shipped to the GPC.

Currently, AC data for GMS are the only ones received on media (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 currently received on media, except for the BC data, the B2 data from MSC and CSU, and the correlative data, which are received via Internet. The ftp delivery of B2 data by EUM is in final testing. Delivery by ftp of all data (except DX) from the GPC to NASA Langley is underway. Delivery of data to ICA by ftp is now being tested. The final version of the new dataset naming convention was distributed to all centers.

Final migration from the mainframe computer has been completed. Now we are beginning the complete copying of our data archives to more modern and denser media.

NOAA-14 B2 data have been received through December 00. Production of NOAA-14 (preliminary) B3 data is complete through December 00. Final B3 data have been produced through December 00.

NOAA-15 B2 data have been received for January 99 through July 00 (the last). Because of the changes in spectral response (visible channel) and the switching of channels (for channel 3), both the calibration procedure and the B3 processing software will have to be revised for NOAA-15 processing. Also, the cloud detection algorithm will have to be revised before these data can be used.

Deliveries of B2 data from GOES-8 are current. Production of GOES-8 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 99.

Deliveries of B2 data from GOES-10 are current. Production of GOES-10 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 99.

Deliveries of B2 data from METEOSAT-5 (at 63E) are current. Production of METEOSAT-5 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 99.

Deliveries of B2 data from METEOSAT-7 are current. Production of METEOSAT-7 (preliminary) B3 data is compete through December 99. Final B3 data have been produced through December 99.

Deliveries of B2 data from GMS-5 are current. Production of GMS-5 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 99.

TOVS correlative data processing is complete through April 98. Another error in the TOVS processing was discovered that also affected the near surface temperature. All of the errors have been corrected for the TOVS data for 94 through 97. We are still awaiting completion of the documentation of the TOVS format change in 98 from NOA.

Production of the ice/snow correlative dataset is complete through December 99.

DX/D1/D2 data processing is complete through December 95. These data are now being delivered. All data products are currently delivered on media to the ICA, but are delivered by ftp to NASA Langley.

Two CDs of D2 data are now available from NASA Langley, covering 83-88 and 89-93.

A completely re-designed ISCCP Web site was released. This new design features much more data and documentation, including many more analysis plots of the ISCCP results, and a separate Web site for the GEWEX Cloud System Study -- Data Integration for Model Evaluation. Data now available on the Web site are monthly mean data for July 83 through December 95 and climatology results based on the period July 83 through December 95. A new dataset characterizing the mesoscale cloud optical thickness variability that can be used to estimate the non-plane-parallel radiative effects in a GCM has been posted to the site. During the next month, many more datasets will be added and the cloud climatology extended. The ISCCP World Wide Web Home Page can be accessed at URL

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-14 remained good. METEOSAT-6 and GOES-11 are in stand-by mode. NOAA-16 is operating in parallel with NOAA-14. The start of FY-2B operations was planned to occur in January 01, but no report has been received.

* Delivery backlogs for B2 data (NOAA-14/16 = 4 months).

* Delivery backlog for B3 data = 10 months (with respect to planned schedule). B3 data for 198 months have been archived.

* Delivery backlog for DX/D1/D2 data = 58 months (with respect to planned schedule). D1/D2 data for 150 months have been archived.
