* Higher max wind gust singular value in database may be due to thunderstorm interference:
  37.3 m/s on 2018-10-23 18.05 shower. 48.4 m/s on 2020-06-26 18.13 (UTC).

NOTE: Max/min values on the web page may differ since they include 
short term momentary values.

Weather station blog
--------------------
2025-01-09  The weather station is getting old, the sensors do not always work correctly.

2024-06-05  Redesign of web page since Google Chart is no longer available.

2022-04-07  For a month the rain gauge has been out of order.
            There has been rain and melting snow, but has not been registred.

2021-07-27  Power outage during thunderstorm stopped the weather computer -
            so we missed to log the really heavy rain in the late afternoon.

2021-03-06  Pressure sensor got new batteries! And recalibration against nearby airport.
            Weak batteries caused low baro values earlier.

2021-01-31  Barometer sensor re-calibrated to nearby airport pressure.
            So curves will bump up from about 9.30 UTC today.

2021-01-01  Barometer sensor calibrated to nearby airport pressure, +10 hPa.
            So curves will bump up from about 11 UTC today.

2017-12-11  Snow season has really begun, so no rain readings in some time.
            When milder, snow on rain gauge can melt and give delayed response.
            Also, heavy snow and low temp might freeze wind readings incl vane.

2017-10-28  Low barometer readings (low battery) from 2017-10-28 13Z to 2017-10-29 13Z

2016-11-08  Calibrated pressure sensor against ESMX airport (lowered 1mb).

2016-11-06  Wet and cold weather: wind speed sensor freezes, 
            intermittent function.

2016-08-29  Outdoor sensors (rain gauge and temp/hum) cleaned after 5 years
            (needed ;-) caused some false rain and humidity values today.

2016-02-09  Where did the winter go? Rain gauge uncovered early, in operation

2016-01-01  Rain gauge covered in winter due to freezing and not fill it with
            snow (that is not measured anyway)

2015-08-29  Weather station reinstalled after SD card and db backup failure
            Weather database lost from 14 June-29 August.

2015-03-01  Rain gauge in operation again, early - mild winter

2014-12-22  Rain gauge closed in winter due to freezing 
            (but cover seems to be leaking jan 2015)

2014-09-28  Recreated Raspbian and wfrog due to SD card problems
            Now using sqlite db instead of mysql on the little Raspberry Pi

2014-03-01  Rain gauge in operation again, early - mild winter

2014-01-18  Weather station restarted - now on Raspberry Pi with log in sql db 
            Rain gauge closed (winter now!)

2013-12-30  Weather station halted - the old NSLU2 lacked muscle to handle 
            the 2-year csv log file

2013-12-24  Rain gauge in operation again since it is so mild outside
2013-11-24  Rain gauge closed in winter due to freezing
2013-04-09  Rain gauge in operation after winter
2013-03-24  Added more sensors och diagrams (indoor, furnace, cellar, freezer)
2012-12-29  Webcam exchanged (from Creative IM Pro to Logistech), they wear out
2012-11-29  Rain gauge closed in winter due to freezing
2012-04-22  Thunderstorm flash upset wind /rain values ca 16:05; adjusted
2012-03-01  Rain gauge mounted, low funnel added on top for calibration
2012-02-26  Software upgraded to Linux Debian 6 and wfrog 0.8.2
2011-12-04  Rain gauge taken in for winter season
2011-04-04  Rain gauge mounted outdoor
2011-03-11  Weather station started (no rain gauge)
