vimt - vertically integrated moisture transport

Scripts to calculate and plot the vertically integrated moisture transport using ERA-Interim data

Data

Downloaded data from https://apps.ecmwf.int/datasets/data/interim-full-moda/levtype=sfc/

The following variables are needed:

• "Vertical integral of eastward water vapour flux" (p71.162)
• "Vertical integral of northward water vapour flux" (p72.162)
• "Vertical integral of divergence of moisture flux" (p84.162)
