No time to translate them now... but following are 6 page about exceptionnal weather events in France, one page for each year.

1914
1915
1916
1917
1918
1919

It also gives the variation to the climatology normal, both for temperature and rainfall for each month of the different years.
(but you need the climatology normal to use them)

Here, you can find a monthly climatologie for France (Normal 1960-1990... but for rainfall distribution, it's not very far from 1900-1930)
You have:
- Monthly total rainfall
- Monthly rainfall days
- Monthly sunny hours
- Monthly sunny days
- Monthly winddy days

I still have to find Monthly temperature normals maps for 1900-1930

Viktor

I found a page where you probably can find what you're asking: Here
This is daily meteo, including Air Pressure, Cloud Cover, Humidity, temperatures (min, max and mean), Rainfall, Snow and Sunshine hours.

If you want, I can sort the data per station location (on the map) and years and send you the result.

The translation of the previous pages I linked would be also usefull to retrieve exceptionnal events.

yes please!
As about map location - it would be enough to split front by sectors, as channel coast/flanders/center/Verdun - it would be more than enough.
Thanks!

I sorted the data... it was quicker than I expected.
..... not much data is usefull...

Only 1 station get full daily data for daily Minimum, maximum, mean temperature and rainfall from 1914 to 1919, it is Paris.
For Rainfall, there are 2 more stations with usefull data:
- Bretigny-sur-Orge (N 48°36'00", E 2°19'36"), too close to Paris to really help
- Chatillon-sur-Seine (N 47°50'54", E 4°34'54"), who could be representative of the Southeast corner of the map.

My guess is that for rainfall, the 2 usefull stations would be sufficient (cut the map in 2 in diagonal and it will tell if it's a rainy day in each part)
For temperature, Paris only isn't sufficient to represent to whole map. In order for the Paris series to be usefull, a map (showing big regions, around 5 areas to represent the different climate zones) with average temperature differences with Paris per Month could do the job... I'll try to find that.

Anyway, I'll send you the files I sorted (and reduced to the 1914/1919 period) by mail this WE.

I also still have to translate the previous links

I finally translated the links for the exceptionnals weather events on the period.
I put it there... in case if anyone interested.

Rainfall is given in mm, tempeature in ° Celcius and ground pressure in mercury mm.

Maybe some usefull info from Belgium there (in french) :

http://www.meteo.be/meteo/view/fr/1078912-Evenements+marquants+depuis+1901.html

The useful links are on the left. I don't know anything about climate so I didn't know what to look for. I hope it could help for the northern part of the front

Boosher posted a nice info link at IL2 UBI forums:

We have a question about british awards:

Britans 2nd highest award is O.B.E. - Order of the British Empire (The Most Excellent Order of the British Empire).It has 3x grades:

M.B.E. - Member The Most Excellent Order of the British Empire (silver)
O.B.E. - Officer The Most Excellent Order of the British Empire (gold)
C.B.E. - Commander The Most Excellent Order of the British Empire (gold with details)

so the question is - we know, that M.B.E. and O.B.E. is the same in size - does C.B.E. size the same as prev one grades? Also - how does C.B.E. wears? On the neck or on the chest?

Thanks!

Were OBE, MBE and CBE given as Military awards in WWI?
They are normally a public service award these days. I would have expected they were the same back in 1914-18. The sort of thing you'd give to someone not in the military who excelled at what they were doing.


ADDED:

Got this from Wiki http://en.wikipedia.org/wiki/Order_of_the_British_Empire


Off particular note in the Wiki article, that I think is relevent for you Viks

VikS, to support what Brigstock has added above, I checked the book A Contemptible Little Flying Corps, by I. McInnes & J.V. Webb, which list the commissions, appointments, and awards for over 1400 RFC/RAF personnel who fought in WWI, and of the 55 men with references to having received an M.B.E., O.B.E., and/or C.B.E., all were awarded post-war (the earliest coming in 1919).

It would appear that WWI RAF veterans only received these awards after the end of the Great War.
