Detailed Description

template<typename OBS>
class oops::interface::ObsErrorBase< OBS >

Base class for OBS-specific implementations of the ObsError interface.

interface::ObsErrorBase overrides oops::ObsErrorBase methods to pass OBS-specific implementations of ObsVector to OBS-specific implementations of ObsError.

Note: subclasses need to provide a constructor with the following signature:

ObsErrorBase(const eckit::Configuration &config, OBS::ObsSpace &obsspace,
             const eckit::mpi::Comm &timeComm);

and pass timeComm to the constructor of this class.

Member Function Documentation

◆ getInverseVariance()

template<typename OBS >

virtual std::unique_ptr<ObsVector_> oops::interface::ObsErrorBase< OBS >::getInverseVariance ( ) const

pure virtual

Return the vector of inverse obs error variances.

Here is the caller graph for this function:

◆ getObsErrors()

template<typename OBS >

virtual std::unique_ptr<ObsVector_> oops::interface::ObsErrorBase< OBS >::getObsErrors ( ) const

pure virtual

Return a copy of obs error std. dev. If this ObsVector_ is modified (e.g. by obs filters), it should be passed back to update() to ensure the covariance matrix stays consistent.

Here is the caller graph for this function:

◆ inverseMultiply() [1/2]

inlinefinalvirtual

◆ inverseMultiply() [2/2]

template<typename OBS >

virtual void oops::interface::ObsErrorBase< OBS >::inverseMultiply ( ObsVector_ & dy ) const

pure virtual

Multiply a Departure dy by \(R^{-1}\).

Implements oops::ObsErrorBase< OBS >.

◆ inverseVariance()
