[Bldg-sim] Weather Station recommendations

[David Reddy via Bldg-sim]

Vikram,

At least for solar radiation, my thesis work included a brief side-track 
into comparing the precision of Davis's solar sensor 
<http://www.davisnet.com/product/solar-radiation-sensor/> to a classic 
Eppley pyranometer 
<http://www.eppleylab.com/instrument-list/standard-precision-pyranometer/> 
in measuring global horz radiation (GHorz).  I also compared these 
measurements to the values in a commercial AMY weather file. I found 
really good correlation between the two sensors under a range of 
conditions for a site in Bellingham, WA.  For this reason, I would not 
hesitate to use this sensor for a project-based weather station.  
Davis's VantageProPlus 
<http://www.davisnet.com/solution/vantage-pro2-plus/> comes with this 
sensor, but I think you can add it on to some of their other stations as 
well.  The sensor outputs a voltage proportional to the solar radiation, 
so really, it can be used with any DAQ system that is good at measuring 
DC voltage.  Some of the personal weather stations in the Weather 
Underground network report solar radiation and the other data you are 
seeking, so you might look around for one of those in the area first 
before starting your own.

One product I've been tracking is BloomSky 
<https://www.bloomsky.com/product>.  I think it would be really cool if 
this product included a solar radiation sensor, or alternatively, 
included a calculation of cloud cover from the images it collects, which 
in turn could be used in algorithms to estimate GHorz (Joe Huang's idea, 
not mine).
