Re: How to obtain/plot/analyze data
Dear Anonymous,
Particularly because you are mentioning that you will have additional questions, may I suggest obtaining an account here at reanalyses.org and posting your question as a new page under the Ocean or under the Observations area?
Then, responses can be added to your page (either by you or the responder).
Instructions for how to make a page appear under a Help menu item visible after you log in.
Please let me know if I can provide more information.
best wishes,
Re: How to obtain/plot/analyze data of solar radiation
Dear Sir,
is it possible to obtain long series of daily short/long wave radiations measurements for mediterranean bacin and particularly for Egypt?
Thank you for your kind reply

Re: How to obtain/plot/analyze data of solar radiation
Dear Giuseppe,
For what time period are you interested in data?
For data from reanalyses, please see the output lists at each of the reanalysis data providers
http://reanalyses.org/atmosphere/overview-current-reanalyses
Almost all (if not all) of the reanalysis datasets provide both of these variables. You will need to subset them yourself, however. For reanalysis datasets that are opendap enabled, you can use something like "ncks" (http://nco.sourceforge.net/) to select only particular gridpoints.
However, these are not "measurements". For this, you will need to consult with experts on these variables. The Baseline Surface Radiation Network (http://bsrn.awi.de/stations/maps.html) might be a good place to start to get some possible data sources (http://bsrn.awi.de/services/contact.html).
Please respond back with additional questions if we can be of more help.
best wishes
Re: How to obtain/plot/analyze data
For the marine surface go to http://rda.ucar.edu/datasets/ds540.0/ - sign in go do data access and create a subset - try it as often as you like.
For 20C reanalysis, http://rda.ucar.edu/datasets/ds131.1, do as above
For the ISPD, noted above, go to http://rda.ucar.edu/datasets/ds132.0, do as above
For global surface observations, 1999 - ongoing, go to http://rda.ucar.edu/datasets/ds461.0, do as above
There are many other option in the Research Data Archive - look around.
Re: How to obtain/plot/analyze data
From the reanalysis datasets, see https://reanalyses.org/atmosphere/how-obtainplotanalyze-data for many options. Please post there with more questions about obtaining variables from reanalysis, and include more details: what time resolution, what period, what region?
Re: How to obtain/plot/analyze data
For directly measured observations, see some links at http://reanalyses.org/observations/surface if you are interested in surface measurements.
For pressure, in particular, the International Surface Pressure Databank http://reanalyses.org/observations/international-surface-pressure-databank may be helpful.

How to obtain long term time series temperature, pressure and humidity data for any location...
Thanks and regards,
