Revised April, 1999 VIII.15DOE-2.1E Documentation Update: Weather ProcessorUsing Standard Formats for Measured DataAs an alternative to using the OTHER subroutine for measured or nonstandard data, one can convert the measured/nonstandarddata into one of the standard formats and then run the DOE-2 weather processor on that format. For weather with no solar data,convert to the TRY format described below under “TRY Format,” and then PACK with the weather processor using TRYSLM.Only the following TRY data fields need be filled (all unfilled fields should contain 9's):hourdaymonthyearstation numberdry-bulb temperaturewet-bulb temperaturedew point temperaturewind directionwind speedstation pressuretotal sky covertype of lowest cloud layerpresent weatherFor data sets with measured solar data, if global and direct are known, use the TMY2 format, described below under “TMY2Format.” The only hourly fields that need to be filled are:hourdaymonthyearglobal horizontal radiationdirect normal radiationopaque sky coverdry-bulb temperaturedew point temperatureatmospheric pressurewind directionwind speedpresent weatherIn the TMY2 header record, all the data items should be filled. For data sets with global horizontal solar data and relativehumidity instead of wet-bulb/dew point, use the DOE-2 measured data format described below.Using the DOE-2 Measured Weather FormatMeasured weather data can be put in the DOE-2 measured weather data format. This format uses metric units and contains themost commonly measured weather variables. For instance the format uses relative humidity rather than wet-bulb or dew-pointtemperature and global horizontal solar rather than direct & diffuse.Format:The file must be 8760 records in length, each record being 80 characters long.Item Columns Format Unitshour 1 - 2 I2day 3 - 4 I2month 5 - 6 I2year 7 -10 I4drybulb 11-20 F10.1 Centigraderelative humidity 21-30 F10.2 a fraction, 0.0 to 1.0atmos. pressure 31-40 F10.1 millibarstotal horiz. rad. 41-50 F10.0 watts/m2wind speed 51-60 F10.1 m/sWind dir. 61-70 F10.0 degrees from north (north=0;east=90)sky cover 71-80 F10.1 a fraction 0.0 to 1.0All quantities must be filled.
