% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 44211 % Primary Name: HANOI/GIALAM % Record Type: TAVG % Country: Vietnam % Latitude: 21.03300 +/- 0.00050 % Longitude: 105.85000 +/- 0.00050 % Elevation (m): 12.00 +/- 0.05 % # of Months: 50 % % IDs: gsod - 488193-99999 % icao - VVGL % usaf - 488193 % % Sources: Global Summary of the Day % % Site Hash: a5c2f7e908b4477151c4b83b9668758f % Raw Data Hash: 51fb58a57e1772249ff3113ac5e6fead % Adj Data Hash: dd3710a1c5c9cad688102118abc754ff % % 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 1983 9 NaN NaN NaN NaN NaN NaN 26.510 0.621 1983 10 NaN NaN NaN NaN NaN NaN 23.331 0.452 1983 11 NaN NaN NaN NaN NaN NaN 18.294 -0.879 1983 12 NaN NaN NaN NaN NaN NaN 13.885 -1.717 1984 1 NaN NaN NaN NaN NaN NaN 11.365 -2.632 1984 2 NaN NaN NaN NaN NaN NaN 13.706 -1.755 1984 3 NaN NaN NaN NaN NaN NaN 19.068 0.113 1984 4 NaN NaN NaN NaN NaN NaN 23.418 0.728 1984 5 NaN NaN NaN NaN NaN NaN 25.543 -0.782 1984 6 NaN NaN NaN NaN NaN NaN 27.180 -0.223 1984 7 NaN NaN NaN NaN NaN NaN 27.923 0.087 1984 8 NaN NaN NaN NaN NaN NaN 27.074 -0.049 1984 9 27.245 -1.022 1 0 NaN NaN 25.676 -0.213 1984 10 24.808 -0.450 1 0 NaN NaN 21.737 -1.142 1984 11 22.886 1.334 1 0 NaN NaN 20.547 1.374 1984 12 18.093 0.112 1 0 NaN NaN 14.482 -1.120 1985 1 13.317 -3.059 1 0 NaN NaN 12.056 -1.941 1985 2 18.833 0.994 1 0 NaN NaN 15.737 0.276 1985 3 19.342 -1.991 1 0 NaN NaN 16.094 -2.861 1985 4 23.372 -1.698 1 0 NaN NaN 21.105 -1.586 1985 5 29.076 0.372 1 0 NaN NaN 26.945 0.621 1985 6 30.296 0.513 1 0 NaN NaN 27.571 0.168 1985 7 29.895 -0.320 1 0 NaN NaN 27.709 -0.127 1985 8 29.298 -0.204 0 0 29.298 -0.204 27.136 0.012 1985 9 28.143 -0.124 1 0 NaN NaN 25.490 -0.398 1985 10 26.379 1.121 1 0 NaN NaN 23.486 0.608 1985 11 22.644 1.091 1 0 NaN NaN 19.902 0.728 1985 12 19.193 1.213 0 0 19.193 1.213 15.649 0.048 1986 1 17.609 1.232 1 0 NaN NaN 14.577 0.580 1986 2 16.087 -1.752 1 0 NaN NaN 14.637 -0.824 1986 3 20.647 -0.687 1 0 NaN NaN 19.558 0.603 1986 4 26.183 1.113 1 0 NaN NaN 23.581 0.890 1986 5 27.136 -1.567 1 0 NaN NaN 25.934 -0.390 1986 6 29.652 -0.130 0 0 29.652 -0.130 27.336 -0.067 1986 7 30.088 -0.127 0 0 30.088 -0.127 27.586 -0.250 1986 8 30.034 0.532 0 0 30.034 0.532 27.393 0.270 1986 9 28.765 0.498 1 0 NaN NaN 25.803 -0.085 1986 10 25.159 -0.099 1 0 NaN NaN 22.201 -0.678 1986 11 21.717 0.165 0 0 21.717 0.165 18.789 -0.384 1986 12 19.282 1.301 0 0 19.282 1.301 16.774 1.172 1987 1 20.403 4.027 0 0 20.403 4.027 16.757 2.760 1987 2 20.167 2.327 0 0 20.167 2.327 18.655 3.195 1987 3 22.205 0.871 0 0 22.205 0.871 22.119 3.164 1987 4 25.016 -0.054 0 0 25.016 -0.054 22.891 0.201 1987 5 30.014 1.311 0 0 30.014 1.311 27.666 1.341 1987 6 29.769 -0.013 1 0 NaN NaN 27.605 0.202 1987 7 30.356 0.141 0 0 30.356 0.141 28.116 0.280 1987 8 29.737 0.235 0 0 29.737 0.235 27.169 0.046 1987 9 28.453 0.186 1 0 NaN NaN 25.831 -0.057 1987 10 25.368 0.110 1 0 NaN NaN 23.667 0.788 1987 11 21.851 0.299 0 0 21.851 0.299 19.292 0.118 1987 12 17.941 -0.040 1 0 NaN NaN 14.078 -1.524 1988 1 17.928 1.552 1 0 NaN NaN 15.542 1.545 1988 2 15.808 -2.031 1 0 NaN NaN 15.242 -0.218 1988 3 16.853 -4.481 1 0 NaN NaN 17.061 -1.894 1988 4 22.751 -2.319 1 0 NaN NaN 21.444 -1.247 1988 5 28.305 -0.398 1 0 NaN NaN 27.161 0.837 1988 6 30.549 0.767 1 0 NaN NaN 27.653 0.250 1988 7 29.656 -0.559 1 0 NaN NaN 28.213 0.377 1988 8 28.787 -0.715 1 0 NaN NaN 26.759 -0.365 1988 9 29.984 1.717 1 0 NaN NaN 26.095 0.207 1988 10 NaN NaN NaN NaN NaN NaN 22.175 -0.703 1988 11 NaN NaN NaN NaN NaN NaN 18.654 -0.520 1988 12 17.690 -0.290 1 0 NaN NaN 16.616 1.014 1989 1 NaN NaN NaN NaN NaN NaN 13.069 -0.928 1989 2 NaN NaN NaN NaN NaN NaN 14.833 -0.628 1989 3 NaN NaN NaN NaN NaN NaN 18.579 -0.375 1989 4 NaN NaN NaN NaN NaN NaN 22.881 0.191 1989 5 NaN NaN NaN NaN NaN NaN 25.528 -0.796 1989 6 NaN NaN NaN NaN NaN NaN 27.127 -0.276 1989 7 NaN NaN NaN NaN NaN NaN 27.648 -0.188 1989 8 NaN NaN NaN NaN NaN NaN 27.365 0.242 1989 9 NaN NaN NaN NaN NaN NaN 26.585 0.697 1989 10 NaN NaN NaN NaN NaN NaN 22.842 -0.037 1989 11 NaN NaN NaN NaN NaN NaN 19.486 0.313 1989 12 NaN NaN NaN NaN NaN NaN 15.879 0.277
