Detailed Description

The CDMProcessor is a class for various smaller data-manipulations. Examples are deaccumulation along the time-axis, ...

Member Function Documentation

void MetNoFimex::CDMProcessor::accumulate

(

const std::string &

varName

)

mark a variable for accumulation along the unlimited dimension, i.e. vnew(0) = vold(0) vnew(n) = vold(n)+vold(n-1)

Parameters

varName

name of the variable to de-accumulate

Warning

does not handle fill-values unless those are NaNs

void MetNoFimex::CDMProcessor::addVerticalVelocity

(

)

add vertical velocity to this CDM, using continuity equation on model-levels

void MetNoFimex::CDMProcessor::deAccumulate

(

const std::string &

varName

)

mark a variable for de-accumulation along the unlimited dimension, i.e. vnew(n) = vold(n)-vold(n-1)

Parameters

varName

name of the variable to de-accumulate

Warning

does not handle fill-values unless those are NaNs

virtual DataPtr MetNoFimex::CDMProcessor::getDataSlice ( const std::string &  varName, size_t  unLimDimPos  )

virtual

data-reading function to be called from the CDMWriter

This methods needs to be implemented by the CDMReader. It should provide the data for each variable, either by reading from disk, converting from another CDMReader or reading from an in-memory data-section.

This function should retrieve the whole data for a dataset without unlimited dimension if the unLimDimPos == 0.

Parameters

varName	name of the variable to read
unLimDimPos	(optional) if the variable contains a unlimited dimension (max one allowed) an slice of this position is returned

Exceptions

CDMException

on errors related to the CDM in combination with the underlying data-structure. It might also throw other (IO-)exceptions.

Implements MetNoFimex::CDMReader.

void MetNoFimex::CDMProcessor::rotateAllVectorsToLatLon

(

bool

toLatLon

)

rotate all the vectors from direction in x/y axes to direction in lat/lon axes vectors are detected automatically

Parameters

toLatLon

convert to latLon if true, otherwise, convert latLon to grid-axes

void MetNoFimex::CDMProcessor::rotateDirectionToLatLon	(	bool	toLatLon,
		const std::vector< std::string > &	varNames
	)

rotate the direction given in degree from y axes to direction in lat axes (north)

Parameters

toLatLon	convert to latLon if true, otherwise, convert latLon to grid-axes
varNames	the variable-names containing directions given as angles in degree

void MetNoFimex::CDMProcessor::rotateVectorToLatLon	(	bool	toLatLon,
		const std::vector< std::string > &	varNameX,
		const std::vector< std::string > &	varNameY,
		const std::vector< std::string > &	stdNameX = std::vector< std::string >(0),
		const std::vector< std::string > &	stdNameY = std::vector< std::string >(0)
	)

rotate the vector from direction in x/y axes to direction in lat/lon axes

Parameters

toLatLon	convert to latLon if true, otherwise, convert latLon to grid-axes
varNameX	the x-part of the vector
varNameY	the y-part of the vector
stdNameX	optional new standard_name for x
stdNameY	optional new standard_name for y
