AVHRR Leads-ARI Polar Gridded Brightness Temperatures, Version 1
Entry ID: NSIDC-0026_1


Summary
Abstract: 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.
