CO2, Temperature, Water, and Nitrogen Studies

Efforts will focus on the development of baseline data sources for North America to link with crop-climate models, sensitivity evaluations of models to changes in CO₂, temperature, and water (CTW), and development of future scenarios. Development of the baseline analysis will include the identification of historical climate sets using co-located meteorological stations, nearest meteorological stations, and gap-filled meteorological time series. One of the linkages discussed was the use of raw GCM/RCM output as part of the statistical downscaling methods in order to provide future scenarios for the crop simulation models.

Goals for CTW (CO₂, temperature, and water) model improvement activities

1. Discuss the need for improving crop model performance based on CTW data.
2. Determine best modelling approaches for predicting response to CO₂, temperature, and water.
3. Identify data available for testing and coordinate data sharing, model testing, and resulting papers.
4. Develop teams, by crop, to share data, test and improve crop models.
