Method Detail

getLevel1

double getLevel1()

Get the first vertical level of this GridRecord

Returns:

the first vertical level value

getLevel2

double getLevel2()

Get the second vertical level of this GridRecord

Returns:

the second vertical level value

getLevelType1

int getLevelType1()

Get the vertical level type of this GridRecord

Returns:

vertical level type

getLevelType2

int getLevelType2()

Get the vertical level type of this GridRecord

Returns:

vertical level type

getReferenceTime

Date getReferenceTime()

Get the first reference time of this GridRecord

Returns:

reference time

getValidTime

Date getValidTime()

Get the valid time for this GridRecord.

Returns:

valid time

getParameterName

String getParameterName()

Get the parameter name

Returns:

parameter name

getParameterDescription

String getParameterDescription()

Get the parameter description

Returns:

parameter description

getGridDefRecordId

String getGridDefRecordId()

Get the grid def record id

Returns:

parameter name

getDecimalScale

int getDecimalScale()

Get the decimal scale of the values

Returns:

decimal scale

getTimeUnit

int getTimeUnit()

Get the time unit as a code, which should be Grib2 table 4.4.

Returns:

the time unit as a code

getTimeUdunitName

String getTimeUdunitName()

Get the time unit as a String. Must be able to create a udunit like: String udunit = timeUnit + " since " + refDate So this assumes that any conversion factor is applied to the value

Returns:

the time unit as a String

cdmVariableHash

int cdmVariableHash()

A hash code to group records into a CDM variable

Returns:

group hash code

cdmVariableName

String cdmVariableName(GridTableLookup lookup,
                     boolean useLevel,
                     boolean useStat)

A unique name for the CDM variable, must be consistent with cdmVariableHash

Returns:

unique CDM variable name
