Atmospheric Satellite Observations

where pseudo-relative humidity is defined as water vapor mixing ratio divided by the saturate water vapor mixing ratio of the background state function (Dee and da Silva, 2002). Unlike in spectral space, it is not straightforward to obtain the balanced (slow) part of the temperature ($T_s$) in model grid space by applying the linear balance operator containing the inverse of the Laplacian operator. Instead, a statistical linear regression model between the mass and streamfunction fields was developed to represent approximately the balanced (slow) ...
