getCalendarPeriod

@Nullable
public static CalendarPeriod getCalendarPeriod(int timeUnit)

isLayer

public static boolean isLayer(Grib2Pds pds)

Check to see if this pds is a layer variable

Parameters:

pds - record to check

Returns:

true if a layer

isLatLon

public static boolean isLatLon(int gridTemplate,
                               int center)

isCurvilinearOrthogonal

getLatLon2DcoordType

public static Grib2Utils.LatLonCoordType getLatLon2DcoordType(String desc)

This looks for snippets in the variable name/desc as to whether it wants U, V, or P 2D coordinates

Parameters:

desc - variable name/desc

Returns:

U, V, or P for normal variables, null for the coordinates themselves
