Integrated Surface Data processing has been delayed. This affects Global Hourly data, Global Summary of the Day (GSOD), and Local Climatological Data (LCD). We anticipate data to be updated late this week or over the weekend.

Pollen grains that are washed or blown into lakes can accumulate in sediments and provide a record of past vegetation. Different types of pollen in lake sediments reflect the vegetation that was present around the lake and, therefore, the climate conditions favorable for that vegetation.
