A few notes on the De-clouded Sea Surface Temperatures Image Archive

The images in this database are from the Advanced Very High Resolution Radiometer (AVHRR).

We record approximately 9 AVHRR passes per day with our L-Band satellite dish.

The raw satellite data is processed to sea surface temperature using the Multi-channel Sea Surface Temperature (MCSST) algorithm using SeaSpace Terascan software. For detailed information on this algorithm check out the primer (pdf file) written by our collegue Dr. Frank Monaldo at Johns Hopkins University.

De-Clouding: The images plotted here are de-clouded according to two time-domain tests. The first test is if any pixel is more than 2 degrees Celsius cooler than the median of the satellite passes in the previous 24hrs. The second test is if any pixel is more than 5 degrees Celsius cooler than the monthly climatologies calculated by NSIPP AVHRR Pathfinder and Erosion Global 9km SST Climatology (Casey, Cornillon). A description of this monthly climatology can be found at ftp://podaac.jpl.nasa.gov/pub/documents/dataset_docs/nsipp_climatology.html.

If any pixel is fails either of these tests, all neighboring measurements within 3km are also automatically failed. According to this de-clouding procedure, unusually cold features could be identified as clouds and removed.

Image de-clouding is performed by Dr. Matt Oliver of the University of Delaware. These declouded images are available via OPeNDAP in netcdf format. Visit http://tashtego.marine.rutgers.edu:8080/thredds/cool/avhrr/catalog.html

The AVHRR sensor has a spectral resolution of 5 channels in the visible and infrared spectrum. The spatial resolution of the data is 1km. All time stamps are in Greenwich Mean Time (GMT). GMT is 4 hours ahead of Eastern Standard Time from March to November and 5 hours ahead the rest of the year (daylight savings time is not observed in England).
