The science data obtained by Ultraviolet Imager (UVI)
onboard the AKATSUKI (also known as Venus Climate Orbiter and PLANET-C) spacecraft
are provided on this page.
Instrument Overview
UVI is designed to map the ultraviolet contrast
at 283 nm for observing SO2 and at 365 nm for the unknown absorber.
geometry information (latitude, longitude, local time, phase angle, incidence angle, emission angle, azimuthal angle) at the center of each pixel.
Level 3 (l3b, l3bx)
calibrated, physical values at equally spaced longitude-latitude grid in NetCDF format, derived from l2b data (l3b), and pointing corrected geometry information at the center of each pixel (l3bx).
Cloud Motion Vector (CMV)
CMVs at equally spaced longitude-latitude grid in NetCDF format obtained by using l3b data.
File Naming Convention
Filename is in "CAM_DATE_TIME_KIND_LEVEL_VER.EXT" format.
CAM
Name of the camera: uvi for UVI.
DATE
date in UTC when image taken at in "YYYYMMDD" format, where YYYY is four-digit year (2010 -- 20??), MM is two-digit month (01 -- 12), and DD is two-digit day (01 -- 31): e.g., 20151207 for 2015-12-07.
TIME
time in UTC when image taken at in "hhmmss" format, where hh is two-digit hour (00 -- 23), mm is two-digit minutes (00 -- 59), and ss is two-digit seconds (00 -- 60): e.g., 051952 for 05:19:52.
KIND
kind of filter or image type: 283 for 283 nm filter, dif for diffuser, 365 for 365 nm filter, and sht for shutter image.
LEVEL

VER
version string: v10 for "version 1.0".
EXT
extension that represents file type: fit for FITS file, jpg for JPEG file, png for PNG file, lbl for PDS3 label file, and nc for NetCDF file.
