Vertical dimension

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.

This table lists all layers sorted by domain.

Domain	Acronym	Full name	Definition
Atmosphere	TC	Total column
TrC	Troposphere column
MUS	Mid-upper stratosphere
UTLS	Upper troposphere / lower stratosphere
FT	Free troposphere
PBL	Planetary boundary layer
Near Surface	At the surface (in the air)
Cloud-top	At the cloud top surface
TOA	Top of the atmosphere
LoThermo	Low Thermosphere (From 100 km to 200 km altitude)
HiThermo	High Thermosphere (From 200 to about 500 km altitude)
M	Mesosphere
Ocean	Sea surface	Surface of the ocean
Bulk	Bulk layer (ocean sub-surface)
Upper oc	Upper ocean
Deep oc	Deep ocean
Terrestrial	Land surface	Land surface
Root	Root region of the soil
Deep soil	Deep soil layer
Interior	Interior earth
Outer Space	Ionos	Ionosphere
L1	At Lagrange point L1 (about 1,500,000 km from Earth)
L4-L5	At Lagrange points L4, L5
Geo	Around the geostationary orbit
Leo	Low Earth Orbit altitude range
Meo	Medium Earth Orbit altitude range
Helio	In the whole heliosphere
Sun	Solar surface and atmosphere
Magnet	Magnetosphere
Cross-cutting (depricated)	n/a (2D)	Not applicable. 2D field, no altitude dependence
n/a	Not applicable. No altitude dependence

Horizontal dimension

The “horizontal coverage“ parameter locates where the variable is to be observed in the horizontal dimension. From a list of 8 options, exactly one entry must be specified. The options are: Global; Global Land; Global Ocean; Coastal areas; Regional (the applicable WMO Region/s to be specified in Comments); Sub-regional (area of magnitude 1000x1000 km to be specified in Comments); Local (area of magnitude 100x100 km to be specified in Comments); and Point (specific locations to be specified in Comments).

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"
