NUMBER 117

DATE: 05/05/93

Sector Processing Center (SPC):

During March, NOA, JMA, AES, CSU and ESA processed greater than 87% of A data into B1/B2 data.Normal operations were reported by NOA, JMA, CSU and ESA.AES reported loss of almost two days of data because of a system failure over a weekend.CSU reported the elimination of a persistent noise and line-drop problem in the METEOSAT-3 data by an increase in the signal power from the domestic communication satellite that transmits METEOSAT-3 data.

Special Area Processing Center (SAPC):

No report received.

Satellite Calibration Center (SCC):

The SCC received AC data for March 93 from GMS-4, METEOSAT-3, METEOSAT-4 and GOES-7. BC data for GMS-4, METEOSAT-4 and GOES-7 for January 93 were sent to the GPC this month.

Global Processing Center (GPC):

The GPC continued to receive B2 data, BC data and correlative data in a routine manner.Production of NOAA-11 (preliminary) B3 data is current.Production of NOAA-12 (preliminary) B3 data is current.Production of GOES-7 (preliminary) B3 data is current. The B2 data delivery backlog includes April - June 92.Production of METEOSAT-3 B3 data has not started yet.Production of METEOSAT-4 (preliminary) B3 data is current.Production of GMS-4 (preliminary) B3 data is current.Production of all INSAT-1 (preliminary) B3 data has been completed. All INSAT-1 B3 have been re-calibrated for January 86 - March 89. Tests of the calibration are underway.Production of the ice/snow correlative dataset is current.Software revisions for processing of TOVS after the format changes are still in progress.Asbestos removal and renovations in the GPC building have been disrupting activities for last half of April. The whole computer facility will be shut down for 10 days in early May to complete some work there.

ISCCP Central Archive (ICA):

The ICA continued to receive B1 data from NOA, AES, ESA, CSU and JMA and B3 and C data from the GPC in a routine manner.

The health of GMS-4, METEOSAT-3 (at 75 W), METEOSAT-4, METEOSAT-5, GOES-7, NOAA-11, and NOAA-12 remained good. Launch of NOAA-I is scheduled for June 93.

Stage B3: July 83 - June 91Stage CD: July 83 - December 91Stage C1: July 83 - June 91Stage C2: July 83 - June 91

Delivering the backlog of GOES-7 B1/B2 data for April, May and June 92 to the GPC.

Delivery backlog for B3 data = 15 months (with respect to planned schedule). B3 data for 96 months have been archived.

Delivery backlog for C1/C2 data = 15 months (with respect to planned schedule). C1 data for 96 months have been archived.
