Detailed Description

Outputs a linear combination of variables.

Example 1

obs function: name: LinearCombination@ObsFunction options: variables: [representation_error@GeoVaLs, sea_water_temperature@ObsError] coefs: [0.1, 1.0]

will return 0.1 * representation_error@GeoVaLs + 1.0 * sea_water_temperature@ObsError

Example 2 - multi-channel

obs function: name: LinearCombination@ObsFunction channels: &select_chans 6-15, 18-22 # this line may be needed depending on the filter used options: variables:

name: brightness_temperature@ObsValue channels: *select_chans
name: brightness_temperature@ObsError channels: *select_chans coefs: [1.0, 0.5]

will return 1.0 * brightness_temperature_<channel>@ObsValue + 0.5 * brightness_temperature_<channel>@ObsError
