Today we had our first real thunderstorm, short-lived. Click
on the picture for a full animated GIF showing the progression from
South to North. The blue crosses are the latest strikes, the yellow
dots the older ones. The hashed squares are the location where the
software thinks the storm is mostly located. Watch how these domains
progress to the North. Time is UTC ( = local time - 2).

Our vintage Delta-T logger does not know about leap years... so it
took the 29th Feb as first March. The monthly data file will be
corrected, but the plots (today, last 7 days) will be a bit
strange... best ignore this,as everything is self-healing. |

Trends analysis for 2023 now finished. For the comparison of
the meteoLCD TOC readings with those of Uccle, only the month's Jan
to Nov are used, as the Uccle data are not yet available on the
WOUDC site. The comparison with the "WebUccle" readings covers the
full year. |

There was a remaining contact problem with the pressure sensor,
corrected this morning at 08:00 UTC. I also removed the pressure
correction applied to the Gnuplot CO2 graphs, as the pressure fault
made these plots absolutely wrong... |

The CO2 problem is solved (13:0 UTC); there was a bad contact on the
cable connector to the Vaisala GMP343 sensor. The 7 days plot will
be bad for a week due to the the autoscaling feature of Gnuplot. |

There is a problem with our CO2 measurements starting the 30th
January, Will try to solve asap... |

1. Our old faithful Delta_T datalogger does not store the
year count in its data-time column, so there usually is a mess with
the Gnuplot 7-days plots during the first week (but not with
the "today" plots).
2. Upload dec23.dat
and full year 2023.zip
data into data archive
3. Look
here for a comparison between our total ozone column
(TOC) measurements with those published by the RMI at UCCLE on their
web-site (only common days retained). Theirs is probably a mix of direct sky (DS) and zenith-sky
(ZS) measurements, whereas we only measure DS. As usual ours are not
too bad, no reason to be ashamed of ! And please remember that
meteoLCD is since more than 20 years the only station in Luxembourg
measuring TOC (and recognized by the
WOUDC as station 412). I want especially give thanks to Mike
Zimmer for helping out with these measurements.
