GlobalClimate.m -- Matlab code

Description
This code returns the mean
annual temperature (MAT) and mean annual precipitation (MAP) for any terrestrial lat × long coordinates
using the data set described in New
et al (2000).

Input (at prompt): latitude and longitude (in
decimal degrees with N and E > 0 and W and S <0)

Output: mean annual precipitation MAP (mm
y-1) and mean annual temperature MAT, (degrees C)
