How to calculate evapotranspiration hourly_mm in CR1000_Campbellsci论坛问答

Please

I could help or send the program or calculation of evapotranspiration (Eto in *. CR1) time in mm with a net radiation sensor in the CR1000 logger. (WAS = mps, Temp = C, Hr =%, NR = W/m2).

How to calculate evapotranspiration hourly_mm in CR1000_Campbellsci论坛问答

I only found this schedule for the CR10X, but not for the CR1000, there is some way to make the steps in the calculation of DLD in CR1 file.

Greetings,

新对话如下:

Look up the ETsz() instruction in the CRBasic help or in the CR1000 manual.

新对话如下:

Thank you,

But I can directly replace the value of solar radiation (Rs) for net radiation (NR), or you have to add any additional conversion or formula.

If the initial formula is:

ETsz (Temp, RH, WindSpeed, SolarRad (MJ/m2), 0,0, Altitude, Zw, 0, FP2, False)

It may look like:

ETsz (Temp, RH, WindSpeed, NetRadiation (W/m2), 0,0, Altitude, Zw, 0, FP2, False)

On the other hand as I remove a setsecurity do not know, I have problems to reconfigure my CR1000. There is way to format the code requested by the logger?.

I thank in advance any help you can give ..
