I built an enclosure for the "sunshine RPi" and tried to install everything today; several scripts had to be written, crontabs modified etc.... The today_01.html page has been updated and rearranged slightly to make room for the Sunshine picture, which is updated every 2 minutes. Some teething problems will certainly show up... so thx for your patience!

Samuel DIAZ and No LINSTER are two senior students of our last year. They started in 2022 to create a sunshine logger fetching the signal of our vintage Haenni Solar sensor, converting them to a picture and storing away in a database. All this using a Raspberry Pi4 they programmed in Python. Their responsible teacher was Prof. Marco Goffinet, who teaches physics at the LCD. We made a quick test, which showed everything working. Some pictures and more text asap....

1. The update of the TRENDS section has been finished. The comparison with the Beidweiler readings remains to be done, if the EU database becomes available again.
2. The open-access website "Science of Climate Change" from Norway has published a "vintage" paper that I wrote in 2007 with the late Hans-Georg Beck and two other co-authors on the variations of atmospheric CO2 concentration with latitude (and other factors). Click here.

233 DU... a spectacular low in TOC (total ozone concentration) for this month measured today (see here).
Before spinning into panic, see the Uccle plot of last year TOC's, and notice how fast the changes often are!

Work on all our solar sensors (replacement of dessicant in UVA, UVB, CM21 and CMP11); as they had to be taken off-line for a short time, there are down-peaks in some of the plots.

1. Upload of the January jan23.dat data file to the data archive.
2. The trends analysis of the 2022 data is nearly done; there remains an analysis of the PM measurements to be done. Our TOC (total ozone column) data are again excellent, compared to those made at Uccle by vastly more expensive instruments! Many thx to Mike for helping with the daily measurements.

The 2022_only.xls file with all the readings, daily's and monthly's values at Diekirch, and also several important monthly values from the Meteolux station at Findel airport, has been uploaded into the data archive. The meteoLCDstats file also has been updated to include all stats from 1998 to 2022.

Work on the TRENDS section will start 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. Look here for an overplot of our 2022 Total Ozone Column measurements with those made at UCCLE by the RMI. As usual ours  not too bad, no reason to be ashamed of :-))!
