VHI combines greenness (VCI) and heat stress (TCI); below 40 the crop is under stress.

Benchmark

Against USDA's WASDE

In September the nowcast was closer than the WASDE in 9 of 15 years (15.6% vs 18.9% RMSE). By December, with harvest results in, USDA is ahead (10.8% vs 16.0%).

Below zero: the forecast was under the final crop.

Read with care. USDA forecasts production, so its error also includes area; the nowcast forecasts yield only. Part of USDA's early gap is area, not yield.
