Having finally got my station (10702) online (life got complicated so it sat in the corner for over 12 months) it’s all looking good apart from rain readings which seem to be between 50 and 75% low. It’s showing 5.8mm yesterday and 5.0mm so far today compared to 27mm yesterday and 10mm so far today from a Davis station within 50 metres and with a very similar outlook. A similar difference shows to other stations in the area. Is there some calibration that can be performed?
