Is there possibly someone who could tell me or some place, from which I could find information about 'BarometricTemperature' column in 'WeatherData' table ?
I have no slightest idea about it, and haven't been able to find it from web.

Not sure if this is what you are looking for - but here it is. The BMP280 sensor returns the temperature (where the sensor is located thus called barometric temperature), barometric pressure sea level, altitude and the barometric pressure calculated from altitude. The following link is the data sheet. www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmp280-ds001.pdfThere may be some information in the documentation that will clarify what you are seeking. Bosch has a number of barometric sensors with different capabilities and accuracy. The data returned needs to be massaged to give proper values - look at the bmp280.py code. |

Thanks !
It gave me an answer to technical questions, and at the same time possibly to other of my concerns in this issue.
The abstract of 'barometrical temperature' is not known in scientific sence. It's perhaps only known in this context and by this chip manufacturer. It has no larger meaning 'per se'
I'm anyhow really grateful of this information.

It's the temperature given by the Barometric Sensor as Doxidad said. It's not very good because the sensor is on the chip, which is on the board inside a box. It will read high for sure.
