The project is to fill in the blank columns in this spreadsheet:
The spreadsheet contains a list of airports a long with the city and country the airport is located in. The country is in ISO 2-letter format (e.g. CN = China, US = United States, etc.)
There are two tabs in the spreadsheet, one for climate, which has a separate row for each month of the year for each airport, and another one with just one row per airport.
For the Climate tab: fill in the average low temperature, precipitation amount, average days with precipitation, snowfall amount, and average days with snowfall
For the Traffic tab: fill in the number of passengers per year (use 2013 estimated or 2012 actual data).
All of this information is generally available on the web. For example for the city of Chicago you can get climate data here:
http://en.wikipedia.org/wiki/Climate_of_Chicago (click [show] under the Data section).
Most major cities have a Wikipedia entry like this. For the rest you can search the web.
For the Traffic tab you will need to search airport statistics. In general the website of each airport will have this data. Example:
You may also find lists of airport statistics:
Please list the link of the data source (where you found the data) in each row in the Ref column.
