| - | ====== VWobs.txt ====== | ||
| - | The v-component of wind speed is an optional forcing data. It is the southerly wind and goes south to north. It can be used for calculation of snowfall distribution. | ||
| - | |||
| - | The file is located in the ''forcingdir'' folder. V-component of wind speed (//m/s//) is given for all time steps. No | ||
| - | missing values may exist (program won’t check!). The //VWobs-file// | ||
| - | is read only if ''readvwobs'' is set in [[start:hype_file_reference:info.txt|info.txt]]. | ||
| - | |||
| - | The file may have comment rows in the beginning of the file. These rows have to begin with ''!!''. The first row read is column headings. It holds a text string (e.g. 'date', no spaces allowed) for the first column, and integers in the form of station or subbasin ID numbers for the rest of the columns. | ||
| - | |||
| - | The first column is date-time. The default format is yyyy-mm-dd [HH:MM], where hour and minutes are necessary if the timestep is shorter than one day. The date-time is the beginning of the timestep. It is possible to use another date-time format: yyyymmdd[HHMM]. It is expected for all forcing files, if ''readformat 1'' is set in [[start:HYPE_file_reference:info.txt|info.txt]]. | ||
| - | |||
| - | The second to last columns are wind for all stations or subbasins. The ID number (first row) may be ''vwobsid'' or ''subid''. If ''vwobsid'' is used, several subbasins may use the same wind time series. ''subid'' is defined in [[start:HYPE_file_reference:GeoData.txt|GeoData.txt]]. The order of subbasins in //VWobs.txt// does not have to be same as in [[start:HYPE_file_reference:GeoData.txt|GeoData.txt]]. ''vwobsid'' may be defined in [[start:HYPE_file_reference:forckey.txt|ForcKey.txt]]. | ||

| - | //VWobs_nnn.txt// holds v-component wind speed forcing data for sequence with seqnr nnn. For seqnr 0 //VWobs.txt// is used. | ||
