Greetings Mark!

We apologize for the previous message. As a group, we are setting down and 
investigating open support requests and accidentally replied to your with the 
answer to another. While we're looking at your ticket, did you have any more 
success in getting your dropsonde data?

Again, apologies for the previous email,
