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.

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.
