Also, your state agency may be able to provide the required meteorological data free.
Some states have the data on their web site.
Otherwise, check with us. Generally, we can provide any data that you may be required to use. Generally, we can process your met order in one day and ship it to you by e-mail. Or, if you prefer, create your own data using EPA's MPRM or AerMet programs. If you use data from only two or three different stations during a typical year, we recommend purchasing data from us.
