CLASS Release 4.1 will be available this fall, 2006. Here is a list of major enhancements the new version will contain.
* Search and delivery for historical GOES-AAA and GOES AA data. This will encompass data as early as 1981 on GOES04.
* Enable OPeNDAP server for support of derived product data that is stored in netCDF format.
* Assorted enhancements to data integrity checks.
* Assorted web interface improvements; especially in the order query page.
* Anonymous data download using http.
* Allow push subscribers to manage their subscriptions via web interface.
* Ingest and delivery of MODIS Level 0 data (demonstration project).
The purpose of the SBUV instrument is to measure the solar irradiance and earth radiance in the near ultraviolet spectrum. From these data, the following atmospheric properties can be deduced:
1. The global and vertical distribution of stratospheric ozone
2. The structure and dynamics of stratospheric ozone
3. Photochemical processes and the influence of "trace" constituents on the ozone layer.
4. Long-term solar activity in the Ultraviolet spectrum.
Usable data can only be collected by the SBUV when it is integrated onto an afternoon spacecraft due to solar angle requirements. For more information on the instrument and the dataset description. please go to the NOAA KLM User's Guide - section 3.8.
1. CLASS can now ingest GOES historical data mode AA and mode A. This completes the CLASS enhancements for ingesting GOES historical data as a previous CLASS release incorporated the capability of ingesting GOES mode AAA data.
2. Enhanced subscription services to allow users request digital signatures along with their data.
3. Enabled search and distribution of CoastWatch Swath data. This data that have been ingested by CLASS for the last two years was recently approved by the data provider for distribution. Data available includes all CLASS holdings.
4. Completed automation of the CLASS-NMMR interface.
The 2nd CLASS Users Conference will be held in Boulder, Colorado - August 7-8, 2006. For more information: 2nd CLASS Users Conference.
The Comprehensive Large Array-data Stewardship System now offers subscription services to users who want CoastWatch data on a daily basis. In order to get a subscription account with us, please send an email to firstname.lastname@example.org with the desired subregions and datatypes (listed below), and the satellite (NOAA-15, NOAA-16 or both).

After months of problems caused by high scan motor currents, NOAA-14 AVHRR GAC data stabilized beginning the morning of January 18, 2002. The GAC data continues to look fine as of this writing (January 24, 2002). However, the HRPT data demonstrates a slight problem which causes earth locations to look off by about a half a pixel. This problem is not uniform throughout the data. Additionally, a number of pixel dropouts and bad data points have been observed throughout the HRPT data. We will continue to monitor these issues.
