satellite data precision


New Member
Hi all,

I’m looking at some satellite data files. They are profiles of chemical atmospheric components and each profile has an associate estimate precision. I’d like to calculate some daily zonal average i.e. an average of many (about 400) profiles. The problem is that I’m not sure on the right way to calculate the estimate precision to be associated to my daily zonal average. I’d like to obtain some error bars representing a precision estimate based on single profile precisions, divided by square root of number of values averaged.
Any suggestions???
Thank you in advance
