[edit] Image copyright problem with Image:Radar-angles.png

Thanks for uploading Image:Radar-angles.png. However, the image may soon be deleted unless we can determine the copyright holder and copyright status. The Wikimedia Foundation is very careful about the images included in Wikipedia because of copyright law (see Wikipedia's Copyright policy).

The copyright holder is usually the creator, the creator's employer, or the last person who was transferred ownership rights. Copyright information on images is signified using copyright templates.

[edit] test for me

P_r = \left [ P_t{{ G^2 \lambda^2 \sigma^0}\over{{(4\pi)}^3 R^4}} \right ] \propto \frac {\sigma^0} {R^4}\qquad \qquad \begin{cases} P_r = received\ power \\ P_t = transmitted\ power \\ G_t = gain\ of\ the\ transmitting\ antenna \\ \lambda = radar\ wavelenght \\ \sigma = radar\ cross\ section\ of\ the\ target \\ R = distance\ from\ the\ transmitter\ to\ the\ target \end{cases}

[edit] Picture categories

Pierre, you picture was attached to main meteorology category. If you would like to use it - the best way would be to add it to radar meteorology article? Otherwise we would have hundreds of pictures attached to "meteorology" (not only radar but clouds, etc) Pflatau 15:00, 23 May 2006 (UTC)

In general, pictures on Wikipedia should not be placed in categories. The category system doesn't handle them well. Pictures on Wikipedia should be added to articles, where appropriate. If the goal is to make the picture itself available to the public (as opposed to using it to illustrate any particular article), the picture should instead be uploaded to the Wikimedia Commons [1]. Pictures there can be linked to from Wikipedia articles just as easily as pictures that are actually on Wikipedia, and the Commons' categories are for pictures and other media.--Srleffler 16:05, 23 May 2006 (UTC)

[edit] WKR

I've moved the article to CWKR, per your request and based on various websites (eg - [2] [3]). However, Environment Canada seems to list its own ID for radar sites (see this). Should this be of concern? Mindmatrix 17:24, 14 June 2006 (UTC)

[edit] Ceilometer

I saw this popup in my watchlist and actually read the article. Cna you look at this (2nd last paragraph) and make sure I fixed it correctly. They took ours away and we no longer have the manuals for me to check. Thanks. CambridgeBayWeather (Talk) 09:00, 25 June 2006 (UTC)

Thanks. I didn't know it was you as the anon. CHeers. CambridgeBayWeather (Talk) 12:22, 25 June 2006 (UTC)

[edit] Lightning detector

Thanks for adding the diagrams, Pierre — they look great. I reorganized the text in that section and bit, and would be grateful if you could read it over to make sure I haven't introduced any errors. David 17:54, 6 July 2006 (UTC)

[edit] Image:Freezing rain.png

Question: Why did you put a NO SOURCE on Image:Freezing rain.png when is is clearly marked that it is from ENVIRONMENT CANADA which allow reproduction if source mentionned? Pierre cb 01:16, 16 August 2006 (UTC)

It has no web reference to where it was found. // Liftarn

[edit] Image:Freezing rain.png

Hi,

Image:Freezing rain.png

Your bot removed this image saying it is without source. However, the description is CLEARLY showing that the image is from Environment Canada. As a canadian goverment departement they allow reproduction (see their site). So could you put back this image!

Pierre cb 23:10, 15 August 2006 (UTC)

They may permit reproduction, but that is not the same thing as an any-purpose license. See User:Carnildo/Image FAQ section 1.2. --Carnildo 07:23, 16 August 2006 (UTC)

[edit] Your comments on Wikipedia talk:WikiProject Meteorology

I'm a little confused as to what you are asking. Right now we have a lot of articles about instrumentation and stuff like that (mostly listed in subcategories of Category:Meteorology). Eventually all articles relating to meteorology will be listed here, but this will probably take awhile. -Runningonbrains 06:13, 13 September 2006 (UTC)

[edit] Weather Radar

Hi,

In the radar article you have changed the caption to "Storm front on Doppler radar screen (NOAA)". This is not a Doppler radar display (velocity) but a reflectivity (intensity of precipitation). It is an american media error to subtitute Doppler to Weather radar. Weather radar can be Doppler but a Doppler radar is not necessarily a weather radar. Sorry but I have to correct. Pierre cb 13:27, 29 March 2007 (UTC)

I agree with you on your point that a weather radar can be Doppler, but not necessarily. I was not trying to imply that this was a Doppler image, otherwise I would have said "Storm front on radar's Doppler screen". Rather, I was pointing out the fact that the radar screen belongs to the Doppler radar. Actually, I just did a direct translation of the image file name from German. To prove to you that the radar is indeed a Doppler radar, I'll show you the source of the image, whose caption states it is the "Norman Doppler radar reflectivity display showing squall line." In my haste, I removed the word reflectivity, thinking that the average reader would not understand, but that has obviously caused confusion. Can we change the caption to read:
"NOAA's Norman Doppler radar reflectivity (precipitation intensity) display showing squall line"
or something to that effect? —Gintar77 23:43, 29 March 2007 (UTC)
