Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The start of the growing season (SOS) is derived from the MODIS Terra Vegetation Indices 16-Day L3 Global 1 km SIN Grid data (MOD13A2.V006). The data coverage includes Alaska and part of Canada Yukon from 55°N to 72°N for the years between 2000 and 2019. The algorithm takes 16-day composite NDVI data, performs data stacking, smoothing, and then calculates the SOS metrics' .
