Solar radiation data (15 min int.)


Nichol Mar 6, 2023 03:44 AM

Is it normal if the solar radiation data captured during midnight 00:00 (124 w/m^2)?

That's going to depend on your location. 

Does it get completely dark at your location of measurement? 

Kipp & Zonen have a guide on the instruction sheet for the CNR4
(https://www.kippzonen.com/Product/85/CNR4-Net-Radiometer)
where that value seems to correspond with a fully clouded day. 

Might be a little high if you're near the equator.

That would be infrared can be that high with clouds. Shortwave will be 0 on a completely dark night.

The spike is every day at 00:00 midnight only. Zero reading started at 7 pm to 6 am (Malaysia time)

Does your system switch power on to something around midnight?

It could be that another device connected is using enough current to create an offset voltage on analog ground. Anything using significant power should use G terminals for ground.

Very a great article. I have read many articles but this is the most informative and useful one for me. slither io

No, it's not normal to have a solar radiation reading of 124 W/m² at midnight. Solar radiation should be zero or close to zero at that time because the sun isn't out. It sounds like there might be an issue with the sensor or a data error. It could also be affected by nearby lights, but that seems unlikely to produce such a high reading. You should check the equipment to see what's going on. snake.io

 The presence of strong artificial light sources, such as streetlights or nearby buildings, may interfere with the solar radiation readings. Make sure the sensor is not exposed to any artificial light geometry dash lite sources that could affect its measurements.
