Remote sounding of atmospheric pressure profile from space, part 3: Error estimation

By using the O₂ absorption band near 0.762 μm, remote sounding errors of surface pressure caused by 6 scientific and 9 technical factors are estimated one-by-one. Then, the remote sounding accuracy in clear field of view is estimated. If atmospheric aerosols and the bi-reflectance at the earth surface are measured accurately by means of other ways, the remote sounding accuracy for the surface pressure of 1000 hPa is 1.3-4.3 hPa in circumstances of heavy atmospheric aerosols; on the other hand, 0.9-4.7 hPa for larger surface bi-reflectance and 2.8-15 hPa for smaller surface bi-reflectance, respectively, in circumstances of lightest atmospheric aerosols.
