a, East Antarctica; b, West Antarctica. Solid black lines show results from reconstruction using infrared satellite data, averaged over all grid points for each region. Dashed lines show the average of reconstructed AWS data in each region. Straight red lines show average trends of the TIR reconstruction. Verification results for the continental mean of the TIR reconstruction are RE = 0.34, CE = 0.31 and r = 0.73. Grey shading, 95% confidence limits.
