List of vertical Layers and horizontal Coverages
Vertical dimension
This table lists all layers sorted by domain. In OSCAR, a 'layer' refers to a range of altitude or depth where a physical variable is measured and a requirement for this variable is applicable. This concept allows assigning different requirements for the same variable depending on the considered altitude or depth.

Horizontal dimension
This table lists all 'horizontal coverage' types used in OSCAR to further specify where a specific Requirement is applicable, e.g only over the oceans, at specific points (Airports), regionally or globally.
Name | Definition |
---|---|
Global | Applicable globally |
Global ocean | Globally applicable to oceans and ocean surfaces |
Global land | Globally applicable to land surfaces and over land surfaces |
Costal areas | Globally applicable to coastal areas |
Regional | Applicable in specific WMO regions as defined in "Comments" |
Sub-regional | Applicable in specific areas of typically 1000*1000 km to be defined in "Comments" |
Local | Applicable in specific areas of typically 100 *100 km to be defined in "Comments" |
Point | Applicable at specific locations, e.g. Airports, to be defined in "Comments" |
