Methods, systems, and computer program products for enhancing spatial and temporal resolution of greenhouse gas emission estimates for agricultural fields using cohort analysis techniques are provided herein. A computer-implemented method includes obtaining non-greenhouse gas remote sensing data and contextual information pertaining to agricultural fields; determining cohorts among the agricultural fields by deriving agricultural field-specific features from the obtained data and contextual information; computing agricultural field-level time series of greenhouse gas emission estimates for the cohorts by processing the obtained data and contextual information using a process-based model; calculating bias corrections for the cohorts by processing, using a time series learning model, the time series and background greenhouse gas emission estimates; generating resolution-enhanced greenhouse gas emission estimates for the cohorts based on initial greenhouse gas emission estimates derived from greenhouse gas remote sensing data and the calculated bias corrections; and performing automated actions based on the updated greenhouse gas emission estimates.
