Berkeley Earth Dataset: Seasonality Removed and Quality Controlled
This dataset is the same as "Seasonality Removed" but further removes any values flagged as bad by the quality control processes. This is the dataset used by the Berkeley Earth Averaging Methodology and is recommended for users who do not require that seasonality be preserved.
Quality Controlled
Same as "Single-valued" except that all values flagged as bad via the quality control processes have been removed. This dataset is recommended for users that require relatively clean data and want seasonality to be preserved.
Seasonality Removed
Same as "Single-valued" except that each series has been adjusted by removing seasonal fluctuations. This is done by fitting the data to an annual cycle, subtracting the result, and then re-adding the annual mean. This preserves the spatial variations in the annual mean.
Single-valued
Data have been collapsed so that there is only one time series per location. Quality control procedures have been completed and their output is reported via a series of quality "flags". Users of this data set will have to consider these flags and remove any data they don't want to use. Seasonality is preserved in this data set.
Multi-valued
This includes all time series from the originating datasets. Due to duplication with the same data being reported by multiple agencies, on average there will be 3-4 time series reports with each site. Only limited quality control flagging has been performed at this stage.
The preliminary TAVG files (first posted 10/21/11) can still be downloaded below.
