IRI Climate Forecast and Climate and Society Briefings

Thursday, October 17, 2013 - 11:00am - 12:00pm
Columbia University, Lamont Campus, Palisades, NY, Monell Building

The Climate Forecast Briefing will present the current and predicted ENSO status, the Climate Predictions for the upcoming months, and a discussion on the verifications of our previous forecasts.

Also, Dr. Narendra Das, Research Scientist for NASA JPL in the Water and Carbon Cycle Group will present a talk.

Abstract

SMAP Mission Overview and High Resolution Soil Moisture Product

The important role of surface soil moisture as a state variable, and therefore the initial condition and boundary condition in predictive models in hydrology, meteorology, ecology, and agronomy, is well recognized. Various applications like weather forecasting, climate change prediction, agricultural production, water resources management, drought prediction and monitoring, flood area mapping, and ecosystem health studies require information on surface soil moisture for skillful modeling and forecasting. For example, soil moisture strongly affects plant growth and hence agricultural productivity, especially during conditions of water shortage and drought. Global estimates of soil moisture and plant water stress is be derived from models. These model predictions (and hence drought monitoring) can be greatly enhanced through assimilation of space-based soil moisture observations. Therefore, mapping surface soil moisture with sufficient accuracy over the required ranges of spatial and temporal scales is imperative to fulfill the needs of such applications. The outcomes from these applications have direct impact on human society and the management of our environment.

NASA's Soil Moisture Active Passive (SMAP) mission will fulfill the need many applications by delivering unprecedented high spatial and temporal resolution soil moisture observations. The SMAP mission is under development with a target launch date in late 2014. The SMAP mission will provide high resolution (~9 km) and frequent revisit (2-3 days) soil moisture observations at a global extent.
