% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 33927 % Primary Name: GROSVENOR LANE % Record Type: TAVG % Country: United States % State: MD % Latitude: 39.01670 +/- 0.00005 % Longitude: -77.11670 +/- 0.00005 % Elevation (m): 100.90 +/- 0.05 % # of Months: 18 % % IDs: coop - 183930 % ghcnd - USC00183930 % ncdc - 20009529 % ncdc - 20009533 % % Sources: US Cooperative Summary of the Day % Global Historical Climatology Network - Daily % US Cooperative Summary of the Month % Multi-network Metadata System % % Site Hash: 3f7bc57a4a13d3dce6eca0a724f21695 % Raw Data Hash: cf74d48d21892b0582b27c4478b54f09 % Adj Data Hash: cf74d48d21892b0582b27c4478b54f09 % % 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 1947 8 NaN NaN NaN NaN NaN NaN 24.612 1.051 1947 9 NaN NaN NaN NaN NaN NaN 20.080 0.343 1947 10 NaN NaN NaN NaN NaN NaN 16.109 3.048 1947 11 NaN NaN NaN NaN NaN NaN 6.407 -0.884 1947 12 NaN NaN NaN NaN NaN NaN 0.338 -1.271 1948 1 NaN NaN NaN NaN NaN NaN -3.740 -3.271 1948 2 NaN NaN NaN NaN NaN NaN 0.183 -0.618 1948 3 NaN NaN NaN NaN NaN NaN 7.721 1.920 1948 4 NaN NaN NaN NaN NaN NaN 12.380 0.592 1948 5 NaN NaN NaN NaN NaN NaN 16.813 -0.354 1948 6 NaN NaN NaN NaN NaN NaN 21.736 -0.081 1948 7 NaN NaN NaN NaN NaN NaN 24.164 -0.140 1948 8 22.833 -1.083 0 0 22.833 -1.083 22.928 -0.633 1948 9 19.222 -0.869 0 0 19.222 -0.869 19.526 -0.212 1948 10 12.222 -1.193 0 0 12.222 -1.193 11.778 -1.284 1948 11 9.833 2.189 0 0 9.833 2.189 10.170 2.880 1948 12 3.111 1.148 0 0 3.111 1.148 2.373 0.763 1949 1 5.667 5.781 0 0 5.667 5.781 4.072 4.541 1949 2 5.833 4.678 0 0 5.833 4.678 4.290 3.489 1949 3 7.778 1.622 0 0 7.778 1.622 6.866 1.065 1949 4 11.889 -0.253 0 0 11.889 -0.253 11.450 -0.338 1949 5 17.833 0.312 0 0 17.833 0.312 17.200 0.033 1949 6 22.056 -0.116 0 0 22.056 -0.116 22.412 0.595 1949 7 25.389 0.730 0 0 25.389 0.730 25.909 1.605 1949 8 23.222 -0.694 0 0 23.222 -0.694 23.806 0.244 1949 9 17.667 -2.425 0 0 17.667 -2.425 18.065 -1.672 1949 10 16.000 2.585 0 0 16.000 2.585 15.641 2.580 1949 11 7.333 -0.311 0 0 7.333 -0.311 7.590 0.300 1949 12 3.889 1.925 0 0 3.889 1.925 2.843 1.234 1950 1 7.778 7.892 0 0 7.778 7.892 6.260 6.729 1950 2 NaN NaN NaN NaN NaN NaN 1.181 0.380 1950 3 NaN NaN NaN NaN NaN NaN 3.989 -1.812 1950 4 NaN NaN NaN NaN NaN NaN 10.064 -1.723 1950 5 NaN NaN NaN NaN NaN NaN 16.548 -0.620 1950 6 NaN NaN NaN NaN NaN NaN 21.280 -0.537 1950 7 NaN NaN NaN NaN NaN NaN 22.990 -1.315 1950 8 NaN NaN NaN NaN NaN NaN 22.717 -0.844 1950 9 NaN NaN NaN NaN NaN NaN 18.140 -1.597 1950 10 NaN NaN NaN NaN NaN NaN 13.906 0.845 1950 11 NaN NaN NaN NaN NaN NaN 7.673 0.383 1950 12 NaN NaN NaN NaN NaN NaN -0.468 -2.077 1951 1 NaN NaN NaN NaN NaN NaN 1.466 1.935
