Accurate predictions of hydrometeorological variables such as precipitation, temperature, soil moisture, and runoff are essential in hazard early warning systems (e.g., floods, droughts, and heat-waves) and improved financial decision making systems (e.g., hydro-power, wind energy, and crop yield). We make short forecasts (i.e., 1-15 days), seasonal predictions (1-6 months) as well as climate projections (50-80 years) while remote sensing and ground observations are utilized to fine-tune these predictions.
