Theme 1 – Environment

Climate

Research goal:

Tracks of 150 sample TCs in the North Atlantic during historical period and change of mean PDI between future (2049-2099) and historical (1964-2014) periods obtained from E3SM-1-0.

The Climate Theme aims to provide quantitative understanding of projected climate change impacts across SETx and beyond. Climate change impacts are being integrated both top down and bottom-up across the project. A top-down approach incorporates downscaled and bias-corrected climate projections to high resolution hydrological (Theme 1a) and air quality (Theme 1b) models that quantitatively explore effects of currently projected climate shifts. A bottom-up approach combines a set of sensitivity scenarios with the hydrological and air quality models using a decision scaling methodology that maps meteorological parameters and conditions.

Water

Flood monitoring sites installation, field surveying and maintenance

Research goal:

The Water Theme targets fundamental science questions building understanding of the underlying processes, spatial heterogeneity, and drivers for current and future conditions. The team is quantifying how climate and land cover change will affect flooding patterns, intensity, and frequency in Southeast Texas and how community-driven flood mitigation might alter the local water and carbon cycles.

Tasks:

  • Identify the patterns and drivers of flooding
  • Expand a flood monitoring sensor network for Southeast Texas
  • Develop a modeling framework for future flooding and mitigation
  • Determine the sensitivity of flooding to climate change
  • Determine the sensitivity of flooding to land use change and urban/ suburban growth
  • Understand wetland biogeochemical and ecosystem service responses to land use and hydrological change
  • Identify and catalog flood mitigation through both nature-based traditional infrastructure and wetland restoration.

Air

Research goal:

The Air Theme aims to quantify how future climate scenarios affect air pollution exposures of SETx and how models and measurements can capture the urban scale heterogeneities in air pollution exposures and community impacts.

Tasks:

  • Identify air pollution hotspots through comprehensive mobile air quality observations  
  • Establish stationary monitoring network at community receptor sites
  • Integrate AQ and toxic releases models through intensive mobile and stationary research campaigns
  • Sample soil and model airborne pollutants that may release during floods
  • Predict the risks of acute and accidental toxic releases into local neighborhoods for current and future conditions, flooding events, and other disasters.
