UARS Wind Imaging Interferometer (WINDII) Level 3AL V011 (UARWI3AL) at GES DISC

The Wind Imaging Interferometer (WINDII) Level 3AL data product consists of daily, 4 degree increment latitude-ordered vertical profiles of meridional and zonal wind components, and temperature. The instrument was a Michelson interferometer designed to measure Doppler shifts of spectral lines in the visible between 550 and 780 nm. WINDII was flown on NASA's Upper Atmosphere Research Satellite (UARS) and designed to measure wind, temperature and emission rates in the mesosphere and thermosphere between 80 and 300 km at about 5 km resolution. Data were collected between latitude 40S and 72N and 72S and 40N, alternating each satellite yaw cycle of about 36 days. The WINDII Level 3AL data were processed with the version 11 algorithm.

The WINDII level 3AL product consists of 3 granules per day. A data granule is one WINDII species or subtype per day.

Data are on the UARS standard altitude levels (in km) given by:

z(i) = 5*i for 1 <= i <= 12
z(i) = 60 + (i-12)*3 for 13 <= i <= 32
z(i) = 120 + (i-32)*5 for 33 <= i <= 88

Each of the 3 WINDII granules is accompanied by an additional parameter file, designated as level 3LP. The parameter file, contains additional ancillary and quality information not found in the 3AL files. The data files are available in a binary record oriented format.
