% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 12017 % Primary Name: CHAO-I % Record Type: TAVG % Country: China % Latitude: 34.83300 +/- 0.00050 % Longitude: 110.16700 +/- 0.00050 % Elevation (m): 350.24 +/- 29.87 % # of Months: 21 % % IDs: gsod - 570510-99999 % usaf - 570510 % % Sources: Global Summary of the Day % % Site Hash: 490e2fa1a5c3928508c257b4d3b46d42 % Raw Data Hash: c8b733e16c394287817f12da334f4f5a % Adj Data Hash: 1bf4ed2e478b9b71832609192a4ec0da % % 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 1956 12 NaN NaN NaN NaN NaN NaN -1.593 -1.556 1957 1 NaN NaN NaN NaN NaN NaN -3.002 -0.993 1957 2 NaN NaN NaN NaN NaN NaN -1.985 -2.486 1957 3 NaN NaN NaN NaN NaN NaN 5.861 -0.236 1957 4 NaN NaN NaN NaN NaN NaN 12.537 0.453 1957 5 NaN NaN NaN NaN NaN NaN 15.773 -1.449 1957 6 NaN NaN NaN NaN NaN NaN 20.889 -1.079 1957 7 NaN NaN NaN NaN NaN NaN 23.118 -0.615 1957 8 NaN NaN NaN NaN NaN NaN 24.335 1.620 1957 9 NaN NaN NaN NaN NaN NaN 16.732 -0.845 1957 10 NaN NaN NaN NaN NaN NaN 12.199 0.085 1957 11 NaN NaN NaN NaN NaN NaN 7.482 1.694 1957 12 2.469 0.183 0 0 2.469 0.183 1.739 1.776 1958 1 -2.981 -3.294 1 0 NaN NaN -3.097 -1.087 1958 2 3.075 0.251 0 0 3.075 0.251 1.448 0.947 1958 3 9.983 1.563 1 0 NaN NaN 7.397 1.300 1958 4 15.090 0.683 0 0 15.090 0.683 13.013 0.929 1958 5 20.047 0.502 0 0 20.047 0.502 16.441 -0.780 1958 6 25.089 0.798 0 0 25.089 0.798 21.976 0.007 1958 7 26.470 0.414 0 0 26.470 0.414 23.685 -0.049 1958 8 21.999 -3.039 1 0 NaN NaN 21.072 -1.643 1958 9 21.203 1.303 1 0 NaN NaN 17.725 0.148 1958 10 12.962 -1.476 1 0 NaN NaN 11.090 -1.024 1958 11 6.233 -1.879 1 0 NaN NaN 5.155 -0.633 1958 12 2.777 0.491 1 0 NaN NaN 1.741 1.778 1959 1 -0.708 -1.022 1 0 NaN NaN -2.426 -0.417 1959 2 3.346 0.522 1 0 NaN NaN 0.940 0.439 1959 3 11.418 2.997 1 0 NaN NaN 6.795 0.697 1959 4 16.111 1.704 1 0 NaN NaN 13.075 0.991 1959 5 20.778 1.234 1 0 NaN NaN 15.480 -1.742 1959 6 25.786 1.495 1 0 NaN NaN 21.919 -0.049 1959 7 30.037 3.981 1 0 NaN NaN 25.765 2.032 1959 8 27.707 2.669 1 0 NaN NaN 24.891 2.176 1959 9 NaN NaN NaN NaN NaN NaN 17.766 0.189 1959 10 NaN NaN NaN NaN NaN NaN 14.105 1.991 1959 11 NaN NaN NaN NaN NaN NaN 5.015 -0.773 1959 12 NaN NaN NaN NaN NaN NaN -0.153 -0.117 1960 1 NaN NaN NaN NaN NaN NaN -0.736 1.273 1960 2 NaN NaN NaN NaN NaN NaN 3.871 3.369 1960 3 NaN NaN NaN NaN NaN NaN 7.018 0.920 1960 4 NaN NaN NaN NaN NaN NaN 11.424 -0.660 1960 5 NaN NaN NaN NaN NaN NaN 16.265 -0.957 1960 6 NaN NaN NaN NaN NaN NaN 23.657 1.689 1960 7 NaN NaN NaN NaN NaN NaN 23.293 -0.440 1960 8 NaN NaN NaN NaN NaN NaN 22.299 -0.416
