Datatype

The data types available for SBUV are:

SBUV/2 monthly 1B file (SBUV1B): The 1b Capture Data Set contains (1) all SBUV/2 sensor data and support data necessary for the derivation of atmospheric ozone and solar flux; (2) instrument in-flight calibration data and housekeeping functions for monitoring post-launch instrument changes; and (3) pre-launch calibration factors, and computed current-day instrument calibration and albedo correction factors to adjust the ozone algorithm for actual instrument performance.

SBUV/2 monthly Product Master File (SBUVPMF): The Product Master File (PMF) contains the ozone information derived by the ozone algorithm, located in space and time, other meteorological information developed in support of ozone computation, parameters indicating the validity of the individual ozone retrievals and the radiance information derived from the SBUV/2 measurements.

SBUV/2 daily Product Master File (SBUVPMFD): The product Master File (PMF) contains the ozone information derived by the ozone algorithm, located in space and time, othe meteorological information developed in support of ozone computation, parameters indicating the validity of the individual ozone retrievals and the radiance information derived from the SBUV/2 measurements.

Inventory ID

A unique numerical ID assigned to the data set for CLASS inventory purposes.

UTC

Coordinated Universal Time (UTC) is the international time standard. It is the current term for what was referred to as Greenwich Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich England, which lies on the zero longitudinal meridian. Universal time is based on a 24 hour clock, therefore, afternoon hours such as 4 pm UTC are expressed as 16:00 UTC (sixteen hours, zero minutes).
