** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** THIS PROJECT SUPPORTS THE MISSION OF THE AGRICULTURAL EXPERIMENT STATION BY ADDRESSING THE HATCH ACT AREA(S) OF: SUSTAINABLE AGRICULTURE.CLIMATE, POLLUTION AND OTHER ENVIRONMENTAL FACTORS POSE GREAT CHALLENGES TO AGRICULTURE, FOOD SYSTEMS AND THEIR SUSTAINABILITY. RELIABLE QUANTIFICATION OF THE MAGNITUDE OF THOSE CHALLENGES AND THE UNCERTAINTY IN THIS QUANTIFICATION IS CRUCIAL TO INFORM POLICY, PRIVATE AGENTS AND THE PUBLIC. THE INCREASING AVAILABILITY OF HIGH-FREQUENCY AND HIGH-RESOLUTION DATA HAS THE POTENTIAL TO IMPROVE THIS QUANTIFICATION ASSUMING RELIABLE DATA-DEPENDENT METHODS ARE USED FOR ESTIMATION AND INFERENCE. THE GOAL OF THIS PROJECT IS TO DEVELOP A PUBLICLY ACCESSIBLE TOOLKIT FOR CLIMATE IMPACT ASSESSMENTS THAT INCORPORATES STATE-OF-THE-ART FLEXIBLE, DATA-DEPENDENT ESTIMATION AND INFERENCE METHODS TO MODEL HETEROGENEITY IN CLIMATE CHANGE IMPACTS. WE ALSO PLAN TO DEPLOY OUR METHODOLOGY TO SUBSTANTIVE EMPIRICAL INVESTIGATIONS OF CLIMATE CHANGE IMPACTS ON AGRICULTURE, AS WELL AS TO REVISIT PRIOR STUDIES EMPLOYING OUR NEWLY DEVELOPED TOOLKIT. FROM A MORE GENERAL PERSPECTIVE, GIVEN THAT OTHER ENVIRONMENTAL QUESTIONS IN THE CONTEXT OF AGRICULTURE, TEND TO RELY ON SIMILAR DATA SETTINGS AND OFTEN EMPLOY SIMILAR TOOLS, THE PROPOSED METHODOLOGICAL WORK HAS THE POTENTIAL TO HAVE BROADER IMPLICATIONS FOR SUSTAINABLE AGRICULTURE BEYOND WEATHER AND CLIMATE CHANGE IMPACT ASSESSMENTS.
