Hi, I was studying what exactly the weewx database contains. I'm interested to 2 specific cases: 1) Davis datalogger connected to weewx with Davis datalogger: in this case, if hardware generation archive is set in weewx.conf, I'm pretty sure that in weewx.sdb I will just find the data as they are stored in the datalogger with no modifications. This means that the values are reported as written in the datalogger specifications <https://www.davisinstruments.com/product_documents/weather/spec_sheets/6510_40_44_50_60_SS.pdf> (mean temp, wind dir, wind speed, instantaneous humidity, total rainfall). 2) Davis station connected to weewx with software generation archive set in weewx.conf: in this case, weewx uses loop packets to generate archive records. And here there is my principal doubt: how are these records made? the weewx user's guide <http://www.weewx.com/docs/customizing.htm#Archive_records>isn't clear: it just says:
> For example, for temperature, it's generally the average temperature over > the interval. For rain, it's the sum of rain over the interval. For battery > status it's the last value in the interval. > > Some hardware is capable of generating its own archive records (the Davis > Vantage and Oregon Scientific WMR200, for example), but for hardware that > does not archive data, WeeWX generates them. > So, how are the records calculated? Are the records the average values of all the parameters over the chosen archive interval? This would be obviously the better option, both because in this way there is no loop packet neglected, and because they are data that can be utilized for scientific purposes (instantaneous data every 5 minutes, for example, have no mean for a scientific study). Anyone can help me to solve this doubt? Thanks, Andrea -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
