% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 32743 % Primary Name: CONCORD AIRPORT % Record Type: TAVG % Country: United States % State: CA % Latitude: 37.98330 +/- 0.00005 % Longitude: -122.01670 +/- 0.00005 % Elevation (m): 6.10 +/- 0.05 % # of Months: 28 % % Alternate Names: CONCORD AP % % IDs: coop - 41960 % ghcnd - USC00041960 % ncdc - 20002568 % % Sources: US Cooperative Summary of the Day % Global Historical Climatology Network - Daily % US Cooperative Summary of the Month % Multi-network Metadata System % % Site Hash: 836717de34adddb65e273136c8a733b1 % Raw Data Hash: 572f7a8f5d1add8b274f6fcdbcb14943 % Adj Data Hash: 7983761d6a8221308d474db27295ca5a % % 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 1946 12 NaN NaN NaN NaN NaN NaN 8.370 -0.228 1947 1 NaN NaN NaN NaN NaN NaN 6.038 -2.263 1947 2 NaN NaN NaN NaN NaN NaN 10.830 0.347 1947 3 NaN NaN NaN NaN NaN NaN 12.406 0.765 1947 4 NaN NaN NaN NaN NaN NaN 14.771 1.560 1947 5 NaN NaN NaN NaN NaN NaN 16.964 1.178 1947 6 NaN NaN NaN NaN NaN NaN 19.048 0.854 1947 7 NaN NaN NaN NaN NaN NaN 19.062 -0.527 1947 8 NaN NaN NaN NaN NaN NaN 19.389 -0.135 1947 9 NaN NaN NaN NaN NaN NaN 19.989 0.853 1947 10 NaN NaN NaN NaN NaN NaN 16.346 0.090 1947 11 NaN NaN NaN NaN NaN NaN 10.358 -1.675 1947 12 6.511 -2.367 1 0 NaN NaN 7.971 -0.627 1948 1 8.944 0.364 0 0 8.944 0.364 9.620 1.320 1948 2 8.556 -2.206 0 0 8.556 -2.206 9.047 -1.435 1948 3 9.889 -2.031 0 0 9.889 -2.031 9.631 -2.009 1948 4 11.667 -1.824 0 0 11.667 -1.824 11.682 -1.529 1948 5 15.111 -0.955 0 0 15.111 -0.955 14.191 -1.596 1948 6 18.667 0.193 0 0 18.667 0.193 17.687 -0.507 1948 7 21.111 1.242 0 0 21.111 1.242 19.149 -0.440 1948 8 21.333 1.530 0 0 21.333 1.530 19.090 -0.433 1948 9 19.444 0.028 0 0 19.444 0.028 18.754 -0.382 1948 10 16.333 -0.202 0 0 16.333 -0.202 16.208 -0.048 1948 11 10.667 -1.646 0 0 10.667 -1.646 11.530 -0.503 1948 12 6.167 -2.711 0 0 6.167 -2.711 6.383 -2.215 1949 1 4.000 -4.580 0 0 4.000 -4.580 4.288 -4.012 1949 2 7.167 -3.595 0 0 7.167 -3.595 8.056 -2.427 1949 3 11.056 -0.864 0 0 11.056 -0.864 10.933 -0.708 1949 4 14.444 0.954 0 0 14.444 0.954 14.215 1.005 1949 5 16.222 0.156 0 0 16.222 0.156 15.636 -0.151 1949 6 20.611 2.137 0 0 20.611 2.137 18.668 0.474 1949 7 20.833 0.964 0 0 20.833 0.964 18.828 -0.761 1949 8 20.556 0.752 0 0 20.556 0.752 18.557 -0.967 1949 9 20.333 0.917 0 0 20.333 0.917 19.810 0.674 1949 10 15.167 -1.369 0 0 15.167 -1.369 15.336 -0.920 1949 11 12.944 0.632 0 0 12.944 0.632 13.885 1.852 1949 12 6.611 -2.267 0 0 6.611 -2.267 7.438 -1.160 1950 1 5.833 -2.747 0 0 5.833 -2.747 6.239 -2.061 1950 2 9.222 -1.540 0 0 9.222 -1.540 10.104 -0.378 1950 3 10.444 -1.476 0 0 10.444 -1.476 10.812 -0.828 1950 4 NaN NaN NaN NaN NaN NaN 14.023 0.813 1950 5 NaN NaN NaN NaN NaN NaN 15.205 -0.582 1950 6 NaN NaN NaN NaN NaN NaN 16.914 -1.280 1950 7 NaN NaN NaN NaN NaN NaN 19.611 0.021 1950 8 NaN NaN NaN NaN NaN NaN 20.017 0.493 1950 9 NaN NaN NaN NaN NaN NaN 19.784 0.648 1950 10 NaN NaN NaN NaN NaN NaN 16.815 0.559 1950 11 NaN NaN NaN NaN NaN NaN 14.643 2.610 1950 12 NaN NaN NaN NaN NaN NaN 10.581 1.983 1951 1 NaN NaN NaN NaN NaN NaN 8.223 -0.077 1951 2 NaN NaN NaN NaN NaN NaN 10.111 -0.372 1951 3 NaN NaN NaN NaN NaN NaN 11.161 -0.479
