I wonder what the impact on accuracy will be. I know a few people who collected rainfall amounts and wanted to share that information with some org (can't remember who) only to be turned away because they didn't use the one approved collection device. The approved collection device was expensive and not attractive, but they were told that all the devices had to be identical to make sure the data collected was accurate and that was for something no more complicated than a measuring cup. What happens when the cheap Chinese weather station I get on amazon gives wildly different data from every other cheap Chinese weather station people got on amazon?
