% The data for this station is presented below in several columns and in 
% several forms.  The temperature values are reported as "raw", 
% "adjusted", and "regional expectation".  
%
% The "raw" values reflect the observations as originally ingested by 
% the Berkeley Earth system from one or more originating archive(s).  
% These "raw" values may reflect the merger of more than one temperature 
% time series if multiple archives reported values for this location.
% Alongside the raw data we have also provided a flag indicating which 
% values failed initial quality control checks.  A further column 
% dates at which the raw data may be subject to continuity "breaks" 
% due to documented station moves (denoted "1"), prolonged measurement 
% gaps (denoted "2"), documented time of observation changes (denoted "3")
% and other empirically determined inhomogeneities (denoted "4"). 
%
% In many cases, raw temperature data contains a number of artifacts, 
% caused by issues such as typographical errors, instrumentation changes, 
% station moves, and urban or agricultural development near the station.  
% The Berkeley Earth analysis process attempts to identify and estimate 
% the impact of various kinds of data quality problems by comparing each 
% time series to neighboring series.  At the end of the analysis process, 
% the "adjusted" data is created as an estimate of what the weather at 
% this location might have looked like after removing apparent biases.  
% This "adjusted" data will generally to be free from quality control 
% issues and be regionally homogeneous.  Some users may find this 
% "adjusted" data that attempts to remove apparent biases more 
% suitable for their needs, while other users may prefer to work 
% with raw values.
%
% Lastly, we have provided a "regional expectation" time series, based 
% on the Berkeley Earth expected temperatures in the neighborhood of the 
% station.  This incorporates information from as many weather stations as 
% are available for the local region surrounding this location.  Note
% that the regional expectation may be a systematically a bit warmer or
% colder than the weather stations by a few degrees due to differences 
% in mean elevation and other local characteristics.
%
% For each temperature time series, we have also included an "anomaly" 
% time series that removes both the seasonality and the long-term mean.
% These anomalies may provide an easier way of seeing changes through 
% time.
%
% Reported temperatures are in Celsius and reflect monthly averages.  As
% these files are intended to be summaries for convenience, additional 
% information, including more detailed flagging and metadata, may be 
% available in our whole data set files.
