On May 22, 2013 at 0340 UTC GOES-13 encountered an anomaly suspending imaging and sounding operations. Recovery efforts for GOES-13 continue and the spacecraft health and safety are nominal. GOES-14 has been activated as a back-up. The first GOES-14 scan was ingested by CLASS at 0745 UTC on May 23. For details of the outage please click here.
Attention Suomi NPP Users:
The most recent global NPP operational products are now available in daily tar files for quick and easy downloads at: ftp://ftp-npp.class.ngdc.noaa.gov/. Please see the NPP help page for instructions. Up to the most recent 90 days of data will be available for direct online access.
Attention Metop users (03/26/13):
With the exception of IASI and GOME Level 2 data, all Metop-B level 1b satellite data is now publicly available beginning January 15, 2013 to present. Pre-operational data collected prior to that date remains restricted. Please contact the CLASS Help Desk if assistance is needed.
Attention CORS users (12/2012):
The National Geodetic Survey's CORS data is now available for ordering from the CLASS archive. Older data are currently in the process of being migrated from the NGDC archive to CLASS. While every effort is made to retain data in the original at-sampling rate, there may be cases where only the 30-second decimated rate data exists. For more details select 'Continuously Operating Reference Stations (CORS)' from the product drop down menu and click on Go.
