Multiple Layers, Same Timestamps: Onset of Winter in Maine
Channel: IBM Research
Date: 05/03/2018

Roughly speaking, the normalized difference vegetation index (NDVI) indicates the amount of vegetation at each pixel. This query shows a series of satellite images of NDVI for Maine. The time series shows a clear drop in NDVI values across the whole state around the beginning of December. Often this is due to snow, an intuition that can be roughly confirmed here by the PRISM (historical weather observation in USA) Minimum Temperature Time series that is included in the query.
