Averaging Multiple Columns / Rows If Two Criteria Are Met

I have a dataset consisting of concentrations of parameters (alpha and beta) at different locations over multiple years. I've included an example dataset here.

I need to calculate an average and standard deviation for each parameter that spans multiple locations and years (but not all locations and years).

Example 1: Calculate the average and standard deviation of alpha values from years 2009 to 2012 at locations A and C.

Answer should be: Average of {0.84, 0.47, 0.27, 0.14, 0.36, 0.65, 0.66, 0.85} is 0.53. Standard deviation of {0.84, 0.47, 0.27, 0.14, 0.36, 0.65, 0.66, 0.85} is 0.26.

The real dataset is large, including 7 different parameters and more than 30 locations. I need to perform these calculations for many parameters, so am looking for a formula (or array formula) that will do this in as little cells as possible. Can this be done by formula or will I need a macro?
