Welcome to GUVI!
The Global Ultraviolet Imager (GUVI) is one of four instruments that constitute the TIMED spacecraft, the first mission of the NASA Solar Connections program. The TIMED spacecraft is being built by Johns Hopkins University Applied Physics Laboratory and GUVI is a joint collaboration between JHU/APL and the Aerospace Corporation. TIMED will be used to study the energetics and dynamics of the Mesosphere and lower Thermosphere between an altitude of approximately 60 to 180 kilometers.
GUVI filenames are being changed to handle the larger orbit numbers.
Since TIMED is rapidly approaching the 100000th orbit, we are currently in the process of updating the orbit number field in the names of our files from 5 to 6 characters to handle the larger numbers. Files with the new naming convention and now being made, and older files will be backfilled after reprocessing to the new name format is completed.
The most up to date calibrated products (version 13) are now the default GUVI data products. Details about the changes to the calibration and data products can be found here.
