The EMEP web site offer many possibilities for retrieving data for further processing on your local computer. The site is divided into two main parts:

1. A regional level offering data for the whole EMEP area
2. A national level for retrieving detailed reports for each country

The national level is accessible through the Detailed reports per country link. Some of the data at this level can only be retrieved if you are registered as an EMEP user. This can be done through the Register as an EMEP user link found at the bottom of the page.

Data is organized in various ways:

• As HTML tables
• As text files
• As compressed files

If data is stored as HTML tables, you have the following possibilities for data retrieval:

1. If you are using MS Internet Explorer as browser and want the data copied into an MS Excel spreadsheet, you may simply mark the table by dragging the mouse pointer over it, then copy the table to the clipboard (Ctrl-C). In MS Excel, you create an empty spreadsheet, and copy the content of the clipboard into it (Ctrl-V). This at least works for MS Excel 2000 and MS Internet Explorer 5.0.
2. You may also save the HTML page (with the table) as an HTML file on your local machine. This can be done by selecting 'File->Save as' from the menu in the browser, and make sure that the file type is '.htm' or '.html'. Then you can open this HTML file with a local software tool that knows HTML (for example MS Word 2000).
3. If you have no local software tool that understands HTML, the best option is to save the HTML file as plain text. Select 'File->Save as' from the menu in the browser, and make sure that the file type is '.txt'. You will then get a text file that can be edited in any text editor. You may also open the text file using any software tool that understands plain text files (most of them do somehow).

If you push one of the 'Data download' buttons, this web site will usually send you a plain text file (.txt). Your browser will react to this in different ways, depending on how the browser is configured. You may just see the file in your browser, as if it had been a normal HTML file. The file will probably appear in a monospaced font without any fancy formatting. If this is the case, you can save the file by selecting 'File->Save as' from the menu in the browser. You may also immediately get a 'File save' dialogue box where you can select a file name and directory for the text file.

Compressed file

A compressed file is an archive of one or more ordinary files. It occupies less disk space and uses less time to be transferred over the internet compared to the set of ordinary files it represents. Once received by the user, the compressed file can be uncompressed and the set of ordinary files recreated on the local machine. This web site uses two different formats for compressed files: '.zip' and '.tar.gz'. All compressed files found on this web site will be available in the '.zip' format, which is very popular on PC/Windows platforms. Sometimes also a '.tar.gz' version is found, which is used on many UNIX platforms.

When a compressed file is retrieved by the browser, you will usually be offered the possibility of saving it to your local hard disk. Then you may start up a special software tool for managing and uncompressing compressed files. On Windows platforms this can for example be the WinZip utility. A browser may also be configured so that the WinZip utility (or similar tool) is started automatically when the browser receive a '.zip' file.
