Hello. I'm preparing the inputs for an SWAT model and am having trouble with solar radiation unit conversion. The data supplied is from a Davis Vantage Pro 2 Solar Sensor and records Solar Radiation in W/m^2 every 5 minutes. In SWAT, solar radiation data must be in MJ/m^2 (daily total). Is it possible to convert the supplied data into the units required by SWAT? If so, may I ask how? Any response will be appreciated. Thank you very much

Multiply W/m2 * 3.6 = MJ/m2
