Syntax
MissingValue
Description
Internally, WEAP uses a value of -9999 to represent missing values when reading from a file, and does not include them on charts or tables. Note: most WEAP calculations will not accept MissingValue and will cause an error. For example, if your climate data has gaps, you must fill these gaps in order to use the data for catchment calculations. The gaps can be filled by one of the ReadFromFile methods above (Interpolate, Repeat, Replace), or you can edit the file yourself to fill the gaps. One exception is the comparison of streamflow gauge data to calculated streamflow. No comparison will be made for any timestep for which the gauge data is missing.
Example
If( ReadFromFile(Climate.csv, , , , , Mark) = MissingValue, \Key\Default Wind Speed, ReadFromFile(Climate.csv) )
If the value for a timestep in Climate.csv is missing, use instead the value from the key assumption \Key\Default Wind Speed.
