1. cmdty US Grain Indexes - This is a series of data-driven volume weighted indexes and price assessments, representing continuous calculations of real time market values of physical grain within a proprietary series of rolling delivery periods. Find calculation details on Barchart’s site.

2. cmdty US Production Forecast Indexes - This is a series of actual estimated yield, production, and harvested area for a given area and corresponds to the average number of bushels/acres that are produced/harvested for that area. The models have been created using machine learning techniques and are optimized to the specific areas that we are calculating the data for. Model inputs are derived based on remote-sensing data and weather station collected data. Barchart calculates this value at the lowest possible resolution for a given Country and then aggregates this information up into estimates for each area that sits above that lowest level.
