Using a Solar Radiation meter provides Watts/m, I need to convert to MJ/m-hour for my own ETo calculations.
For the life of me I can't figure it out.
Actual results from the WS (in Wpm2)
-1.0 to ~800
Allowed Range of MJ/m-hour
-6.78 to 27.4
How to convert from Wpm2 to MJ/m-hour???
Thanks

Let me direct you to Table 4.1 in the LI200X-L manual, which shows how to translate a pyronometer's average flux value (W m^-2)that typically use an Average instruction in a DataTable, and convert it to Total Flux Density (MJ m^-2) using the Totalize instruction. Though that's typically done on a daily basis, there's no restrictions on using that same scheme for shorter time periods.
