slow downloads

Does sound like something between your machine and our servers.  We don't throttle connection bandwidth.    Goddard is near Washington, D.C.

Glad things are back to normal :grin:

As for querying for data, you could set up a subscription for the data.

Stefan,There is nothing on our side that would limit your connection speed.  I did see that your IP is doing about 3 times as many file_search requests as file downloads.If you're using file_search in a script, is it because you have a subscription that you're querying?  If so, you...

From the information you've provided we can rule out the assymetric route problem :grin:
There was a modification to the firewall on 20 Jan 2017 that may improve things for you.
Are you still experiencing difficulties?

HICO Level 2 - Rrs data

No.  Not yet at least.  The l2gen program was originally developed for multispectral sensors with the only bands above 720nm used for aerosol retrieval.  Rrs is clamped to 720nm in the code.HICO is the first hyperspectral instrument l2gen can process, and we are still refining that ca...

atmospheric correction quality control for Rrs

The size of the box should be sufficiently large to have statistical confidence in the retrieval, but small enough to ensure that the average measurement is representative of that seen by the in situ data.  If the waters are homogenous, you can use a larger region.  If there is a lot of lo...
