Hi John, Will do, thanks! (I have been testing out subsetting via the TDS for the ESG folks upstairs from me, and I thought they had submitted a bug report, but it sounds like it hasn't happened yet. I'll write up what I've got and send it to you off-list.) Cheers, --Seth On Wed, 28 Aug 2013

Hi Sean, Personally, I would regard that as suspect behavior. I'm of the opinion that it's best practice for a data service to affect the data it operates on in very targeted and transparent way, and that it should pass everything else through untouched. If it doesn't do that, it's harder to

Hi John and all: For sure its a good idea to preserve the CF Conventions attribute if it exists. I will add that to our issue tracker. Remember that THREDDS is a general purpose subsetter, not specific to CF. So we deal with lots of source datasets (eg GRIB) that arent CF. The point is that
