Description/Algorithm

Under subcommand -CREATE, available database values are written to a new record in the MASTER.DB database. These values are generated by PASSREC. Under the subcommand -CLOUD, cloud coverage codes are entered into the database for the appropriate scene. These values are generated via TABLE. The -UPDATE subcommand allows any field entry to be edited.

The following codes are valid for the cloud coverage entered under the subcommand -CLOUD:

CL = Clear, no clouds present CC = Completely cloud covered HZ = Hazy, thin surface clouds PC = Partly cloud covered, scattered clouds 0 = No further processing, too cloud covered, area not useful for products. 1 = Select for further processing, useful for products such as greeness maps. 2 = Half the country is covered by this scene, partly usable, up to the analyst for selection.

For example, CC0 would indicate a country is completely cloud covered, and no further processing of this country should be done from this scene.
