<p>integrated
water vapor transport (IVT) calculated using u-wind, v-wind, and specific
humidity from the European Centre for Medium-Range Weather Forecasts ERA5
Reanalysis Dataset on pressure levels from 1000 to 300 hPa. IVT is calculated
as follows:</p>
<p>IVT =1/g ∫(1000 hPa)^(300 hPa)qV dp<br></p>
