Farmworker communities are vulnerable to heat stress, especially in the hot Central and Imperial Valleys of California. The project will map rural heat islands (RHIs) 
and assess their impact on farmworker communities to develop adaptation strategies, which are critically important for the success of California’s climate action and environmental justice.
We are using modeling data to assess potential changes to climate and agricultural production of the Amazon due to the global increasing greenhouse gas concentrations in the atmosphere. This research is part of the NSF project Land-Climate-Water Feedbacks and Farmer Decision-Making in an Agricultural System .
Wildfires are important disturbances to terrestrial ecosystems that can impact heat and moisture exchanges between the land and the atmosphere for months or years after they occur. We are using model simulations and remote sensing to quantify the effects of wildfires on climate and improve wildfire season predictions.
We are using climate models to assess the effects of global warming on Southern California's winegrape climatic suitability. Our results suggest a significant decrease in suitable land for viticulture in the region due to the decline in the number of cool nights and the increase of growing season heat accumulation.
Terrestrial water storage (TWS) is the sum of water on the land surface and in the subsurface. It includes soil moisture, groundwater, and water stored in plants and snow. The ability to estimate TWS is essential for water resource assessment. Our group has implemented a new atmosphere-land-aquifer coupled model that can simulate TWS variations in S. California.
