MODIS PWV are well correlated with the GPS PWV (2005–2012) with an average bias −0.018 cm.
- •
Estimated peak daily PWV from eight years data varied from 1.7 to 2.05 cm.
- •
Seasonal peak of PWV is ∼1 cm which occurred in summer and 85% of total PWV lies
.- •
MODIS PWV underestimates from GPS during summer with bias −0.095 cm and RMSE 0.215 cm.
- •
MODIS, GPS PWV and rainfall indicate a good correlation during high rainfall in 2006 and 2010.
