A method for generating coherent spatially explicit maps of seasonal palaeoclimates from site-based reconstructions
S. F. Cleator, S. P. Harrison, N. K. Nichols +2
We describe a method for reconstructing spatially explicit maps of seasonal palaeoclimate variables from site-based reconstructions. Using a 3D-Variational technique, the method fi…
