Modelled British river water temperatures (1982-2011) dataset ctrBR8211a. This dataset is a .7z archive (www.7-zip.org); uncompressed size = 2.63 GB. DESCRIPTION This dataset consists of: .\WaterTemperature\images\*.bmp (8 files) .\WaterTemperature\segments\*.csv (20,578 files) + several ASCII text files (.txt) with additional information + data files segments.dbf and citylist.dbf + two custom utilities for data visualisation The two provided utilities run on Windows OS (XP and up); they *may* also run under Wine on Linux and Mac (https://www.winehq.org/). *Showseg.exe displays river segments and associated data on a map *ShowTemp.exe plots river temperature time series per segment Please consult the QuickStartManual for details. ShowSeg.exe can be run on its own. The first time it ever runs, it needs to create a work environment ("Preparing the Map"); please be patient; several small, additional text files will be created. ShowTemp starts its own instance of ShowSeg and closes any other running instances. Multiple instances of each cannot run concurrently. The ShowTemp "Grab" option may not work properly if dpi rescaling is active in the operating system (often used on high-resolution screens to enlarge GUIs). segments.dbf/txt contain the relevant EEA ECRINS data on river segments. Please do not edit or move these files. ECRINS data are copyright-free, provided that source acknowledgements are made. See: http://www.eea.europa.eu/legal/copyright: "Unless otherwise indicated, re-use of content on the EEA website which is the property of the European Environment Agency (EEA) and for which the EEA holds the rights of use, is permitted free of charge for commercial or non-commercial purposes, provided that the source is acknowledged and that the entire item is reproduced." Notes on some segments data fields: OBJECTID links with original ECRINS data sets STRAHLER ECRINS-assigned confluence level CELLID links with NOAA data grid cell (internal) ROW,COL links with MetOffice grid cell CHAIN_ID IDcode of connected segments (single catchment) PENTE river segment slope FNODE_X/Y OS grid easting/northing of segment's upstream terminus TNODE_X/Y OS grid easting/northing of segment's downstream terminus F/TNODE_Z termini elevation in meters L_T2MOUTH downstream distance in km from segment's Tnode to coast SEADIST to nearest NOAA grid cell, in kilometers MINLAKDIST to nearest ECRINS lake centroid, in meters EUCLIDIST Euclidean distance in OS grid between segment's F/Tnode NEXTREC chain pointer (builds CHAIN_IDs) STYPE (C)oastal, (L)acustrine, or (R)iverine INTRNAME from ECRINS Gazetteer (ambiguous) For other ECRINS-extracted fields, please consult: http://www.eea.europa.eu/data-and-maps/data/european-catchments-and-rivers-network/download.pdf Subdirectory .\segments contains model estimates of daily mean river water temperature per segment, for each day, from 10 Jan 1982 to 31 Dec 2011. ASCII files encoding is Windows 1252: Western European. Segment filename structure: S.csv The objectID corresponds to the field of the same name in segments.dbf/.txt (NB segments.txt is generated from segments.dbf by ShowSeg.exe) Each segment file contains 10,948 lines (one per day for the specified period), each terminated by (0D0Ah). Each line contains only the estimated temperature in degrees centigrade. Each file terminates with an marker (1Ah). Subdirectory .\images contains the British coastlines as bitmaps at various resolutions. Please do not edit or move these files; ShowSeg won't function without them. Coastline map data are (c) OpenStreetMap contributors. OpenStreetMap data are free to all; the data are available under the Open Database Licence. See http://www.openstreetmap.org/copyright citylist.dbf is the default list of British cities to be plotted as red dots, it is copyright-free. Up to 255 entries can be accommodated. Upon fist startup, ShowSeg will generate a citylist.txt ASCII file that is easier to edit than the dbf. If changes made to citylist.txt are unsatisfactory, deleting this file will cause ShowSeg to regenerate one from the dbf. Should the dbf itself become corrupted; a reinstallation would be required.
