Detailed Description

This class encapsulates the whole set of RCFs for a project and provides a method for determining which of the RCFs is the best match of a given set of brightness temperatures (scan) taken at a particular elevation.

A set of Retrieval Coefficient Files (RCFs) are currently written by the VB program RCCalc which takes RAOB data and converts it into Templates that describe what that RAOB profile would look like to the MTP instrument if the instrument was used to measure the atmosphere described by the profile.

When the MTP instrument completes a scan of the atmosphere the scan counts are converted to Brightness Temperatures, using these the "best match" RCF is found and it's corresponding Retrieval Coefficients are used to determine the atmospheric temperature profile.

RC_Set_4Retrieval RetrievalCoefficientFileSet::getBestWeightedRCSet	(	std::vector< float >	ScanBrightnessTemps,
		float	PAltKm,
		float	BTBias
	)

Get the Retrieval Coefficient Set from the "best" template weighted according to the flight level of the aircraft and given a set of Scan Brightness Temperatures

Parameters

[in]	is	an array of Scan Brightness Temperatures and is expected to be NUM_OBSVBLSs in length. It is also expected that channel 1 will be in array elements 0-9 with element 0 being the highest scan angle and element 9 is the lowest scan angle. Similarly, channel 2 will be found in elements 10-19 and channel 3 will be in elements 20-29.
[in]	is	the altitude of the aircraft in km at the time that the Scan was taken. [in] is an Brightness Temperature Bias provided by user

Returns

is the weighted average set of Model Brightness Temperatures, RMS values, and Retrieval Coefficients from the template that best matches the input Scan Brightness Temperatures as observed from the input flight altitude.

bool RetrievalCoefficientFileSet::setFlightLevelsKm	(	float	FlightLevels[],
		int	NumFlightLevels
	)

Set the Flight Levels in KM.

Parameters

[in]	is	an array of floating point values indicating the km above sea level of each flight level in each retrieval coefficient file.
[in]	is	the size fo the vector Flight levels should be ordered in decreasing altitude.

Returns

true if levels successfully set, false if not. Assumes that all RCFs in the set have the same flight levels - historically that has been the case, but it may not have to be.
