Accurate large-area inversion method for near-surface air temperature

Provided is an accurate large-area inversion method for near-surface air temperature. The method comprises the following steps that firstly, subpatterns from a first subpattern modelVEC to an fth subpattern modelVEC are obtained; a grid point original data record set sBlkVEC is constructed and normalized; a near-surface air temperature inversion general drawing of each subpattern is calculated; error abnormality points and their adjacent areas are marked in the near-surface air temperature inversion general drawing surfT; an accurate inversion striograph surfT for the near-surface air temperature is figured out by a selective summation algorithm; the areas, true for f=1, 2, 3, ..., of the pixel points (as shown in the description) in the surfT are further processed. By means of introducing a super nonlinear algorithm, the problem that information is fused for the near-surface air temperature inversion is solved, and the satisfying result that inversion error has no connection with cloud cover, landform and te
