Find Accurate Weather Logs for Your Astronomy Observations | Natski

AI Thread Summary
Natski seeks accurate weather logs for astronomy observations, specifically ground temperature, pressure, and humidity, based on latitude and longitude. The discussion highlights a need for tools that can provide this data by inputting geographic coordinates and dates. While some users suggest resources like Weather Underground, the challenge of obtaining elevation data from latitude and longitude remains unresolved. A solution is found in Earthtools, which allows users to retrieve elevation information by entering coordinates in a URL format. This resource effectively addresses Natski's requirements for both weather logs and elevation data.

Hi all,

I have photometry from a number of sources with only very sparse details about the observing conditions at the time. The only information I have is the date, the filter and the longitude & latitude of the observer.

Is there any program or website on which one can enter any latitude & longitude plus a date and it will be able to estimate or reproduce the weather logs for that area? Specifically I need ground temperature, ground pressure and if possible humidity.

Any tips would be very much appreciated,

Natski

For that matter, I cannot find anything that would produce the elevation of a given longitude and latitude and would work well with a script...
 
Thanks, but is there anything where you enter longitude and latitude rather than the name of a place?

Also, the elevation problem remains unsolved. I have found several java scripts on the web but nothing which one could easily link into a code.

Hmm...not sure about lat and long. I think you may have to manually find the nearest town.

...what elevation problem?
 
Hmm that's a great shame... it would make an automated script somehow impossible (or at least from my point of view).

Elevation problem - I am referring to other problem I posed: is it possible to somehow input long & lat and output elevation of that target (i..e altitude above sea-level). I have found java scripts to do this but nothing which could be linked into a script running on my machine.

I had the same trouble finding elevations from lat/long a few months ago. Then I found the above site. It works quite simply, submit the lat and long in the url and it'll return some XML that includes the elevation.

example:

That is excellent, exactly what I was looking for! Thank-you so much.
