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 Noé 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....

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

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. |

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 :-))!
