Retrieval algorithm for CO₂ and CH₄ column abundances from short-wavelength infrared spectral observations by the Greenhouse Gases Observing Satellite

Model estimated CO 2 time series at two surface stations in the southern extra-tropics, compared to CO 2 measurements taken at those stations.. The “GOSAT” line is from an

sensitivity of the retrieval error to the surface pressure error is thus almost twice as large in winter as in summer which is mainly a consequence of the di ff erences in a

For this reason, the remaining test scenarios are used to estimate the sensitivity to aerosol, cloud micro and macro physical parameters which are not part of the state vector but

Thus the maximum of the retrieved surface reflectance error distribution is defined by the a priori error (while the retrieved error for optical depth and e ff ective radius depends

In general, over the cleanest areas (open-ocean and high-latitude regions), the SP2 algo- rithm yields V strat values that are approximately as accurate as the NO2 slant columns

at continental sites, which are attributed to model transport errors within the planetary boundary layer or in the stratosphere or model errors in the seasonal amplitude of

The red points correspond to the tropospheric column-averaged CH 4 mole fraction derived from N 2 O and explicitly using tropopause pressure, the blue to those derived from N 2 O

The framework is based on a mass balance ap- proach and given that for Europe most of the components have been independently estimated, di ff erent accounting schemes may be used
