% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 23898 % Primary Name: CHIANG MAI INTL % Record Type: TAVG % Country: Thailand % Latitude: 18.76700 +/- 0.00050 % Longitude: 98.96700 +/- 0.00050 % Elevation (m): 316.00 +/- 0.05 % # of Months: 13 % % IDs: gsod - 483275-99999 % icao - VTNC % usaf - 483275 % % Sources: Global Summary of the Day % % Site Hash: 825ca6ccdd11fe2bd9f1a2e29dd57007 % Raw Data Hash: 68d555b0c82a7bfe4cd637918fb7772f % Adj Data Hash: 745adb5e6c09fed06a87c37b5d43292c % % 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. % % The Berkeley Earth analysis was run on 15-Nov-2013 19:55:48 % % Raw Data QC Continuity Adjusted Data Regional Expectation % Year, Month, Temperature, Anomaly, Failed, Breaks, Temperature, Anomaly, Temperature, Anomaly 1974 5 NaN NaN NaN NaN NaN NaN 27.271 -1.066 1974 6 NaN NaN NaN NaN NaN NaN 26.791 -0.706 1974 7 NaN NaN NaN NaN NaN NaN 26.974 -0.149 1974 8 NaN NaN NaN NaN NaN NaN 26.522 -0.166 1974 9 NaN NaN NaN NaN NaN NaN 26.155 -0.274 1974 10 NaN NaN NaN NaN NaN NaN 25.910 0.538 1974 11 NaN NaN NaN NaN NaN NaN 23.620 0.220 1974 12 NaN NaN NaN NaN NaN NaN 21.402 0.661 1975 1 NaN NaN NaN NaN NaN NaN 21.516 0.830 1975 2 NaN NaN NaN NaN NaN NaN 23.553 0.336 1975 3 NaN NaN NaN NaN NaN NaN 26.991 0.516 1975 4 NaN NaN NaN NaN NaN NaN 30.085 1.441 1975 5 27.538 -0.795 0 0 27.538 -0.795 27.907 -0.430 1975 6 27.456 -0.036 1 0 NaN NaN 27.087 -0.409 1975 7 26.661 -0.457 0 0 26.661 -0.457 26.836 -0.287 1975 8 26.484 -0.200 0 0 26.484 -0.200 26.403 -0.285 1975 9 26.598 0.174 0 0 26.598 0.174 26.240 -0.189 1975 10 26.260 0.893 0 0 26.260 0.893 25.766 0.394 1975 11 23.635 0.241 0 0 23.635 0.241 23.196 -0.203 1975 12 17.743 -2.994 0 0 17.743 -2.994 18.185 -2.556 1976 1 19.062 -1.620 1 0 NaN NaN 18.796 -1.890 1976 2 22.245 -0.968 1 0 NaN NaN 22.540 -0.678 1976 3 25.983 -0.487 0 0 25.983 -0.487 26.469 -0.006 1976 4 29.095 0.455 0 0 29.095 0.455 29.038 0.394 1976 5 27.901 -0.431 1 0 NaN NaN 27.088 -1.249 1976 6 NaN NaN NaN NaN NaN NaN 27.074 -0.423 1976 7 NaN NaN NaN NaN NaN NaN 27.199 0.076 1976 8 NaN NaN NaN NaN NaN NaN 25.886 -0.802 1976 9 NaN NaN NaN NaN NaN NaN 26.401 -0.029 1976 10 NaN NaN NaN NaN NaN NaN 25.619 0.248 1976 11 NaN NaN NaN NaN NaN NaN 23.219 -0.180 1976 12 NaN NaN NaN NaN NaN NaN 20.756 0.014 1977 1 NaN NaN NaN NaN NaN NaN 21.031 0.345 1977 2 NaN NaN NaN NaN NaN NaN 22.553 -0.664 1977 3 NaN NaN NaN NaN NaN NaN 25.883 -0.591 1977 4 NaN NaN NaN NaN NaN NaN 28.063 -0.582 1977 5 NaN NaN NaN NaN NaN NaN 27.600 -0.737
