Hi there,

I prepared the input files using SUEWS simple in QGIS. When I run SUEWS.exe in cmd window, the message I got was shown below:

The input variables were measured by an eddy covariance system. And the meteorological input file and RunContral.nml were attached for your reference. There was no problem.txt created.

May I ask you guys some advices? Thanks very much!

Best regards, Wenhui

Hi Wenhui, Thanks for reporting this issue.

Problem: If you can have a look at this page, you'll notice your chosen option actually used observed L_down to calculate Qn; while your observed L_down is -999, which might have caused some runtime issue.

Solution: Please change NetRadiationMethod to 0 or 3 and give it another try.

Hi Ting,

Thanks very much for your correction. Now it has been run successfully.

By the way, previously I setting the "NetRadiationMethod" to 1 was referred to this page. The description for No. 5 is " Net all-wave radiation. Required if NetRadiationMethod =1". Now I knew it should be 0 if I would like to use measured Rn directly. Do you think it will be better if revising the website description to prevent the confusion for other users?

Thanks!

Best Wenhui
