Group: Summary

   This data set consists of AVHRR imagery selected from hard copy 'quick look' 
   images to provide the best coverage possible over the Arctic approximately 
   every three days for a three-year period. Level-1B data from NOAA/SDSD have 
   been calibrated and mapped to earth locations, then gridded to 1 km pixels on 
   a basin scale to the polar stereographic projection. The projection is similar 
   to that used by NSIDC to produce DMSP SSM/I polar brightness temperature and 
   sea ice products. Each image was ranked for areal coverage of particular seas 
   and for degree of cloud coverage. Passes covering a large area are generally 
   favored over shorter passes with less cloud cover. The data set was developed 
   in support of the Office Of Naval Research Arctic Leads Accelerated Research 
   Initiative (Arctic Leads ARI). The aim of the Initiative was to develop a more 
   thorough understanding of the oceanography, meteorology, and ice dynamics 
   surrounding formation and evolution of leads in sea ice. The leads ARI field 
   experiment took place from March to April 1992.

   A spreadsheet containing the image rankings is available in hard copy (NOARL 
   Tech. Note 118, April 1991); paper copies of the spreadsheet are available on 
   request. Data set information is available on-line. Data are available via FTP.
