We just tried a query like you were trying and could not reproduced your error. We could order data without any issue (see attached). You may want to retry after clearing your browser's history or can try in another browser.

The SDS "Cloud_Effective_Radius_1621" is "Cloud Particle Effective Radius two-channel retrieval using band 7(2.1um) and band 6(1.6um)from best points". For more information see: https://atmosphere-imager.gsfc.nasa.gov/products/cloud/format-content and https://atmosphere-imager.gs...

We are glad that you find our data archive on the Cloud useful. No, currently there is no plan to migrate MODIS L1A data to the Cloud.

Dear Adam Thurston:
We are working on it and the whole collection should be available in CMR within a week.

The values you listed are correct. The "add_offset" value is a negative value: units = K scale_factor = 0.009999999776482582 add_offset = -15000.0 The following equation should be used to get to the real value: value = scale_factor * ( stored_value - add_offset ) so for a stored integer va...

Somehow missed your post. You may want to explore tools available from LAADS DAAC. The information about these tools can be found here: https://ladsweb.modaps.eosdis.nasa.gov/tools-and-services/#ldope The User Guide for the Reproject tool has an example of first reprojection of the MODIS/VIIRS data ...

Hi Nikolaos, Yes, it appears that the issue lies in how you're calculating the spatial extent. This is how you calculate the bounding box using the horizontal (h) and vertical(v) time number – WestBoundCoord = (10*HorizontalTileNumber) - 180 NorthBoundCoord = 90-(10*VerticalTileNumber) EastBoundCoor...

We are hoping to have NOAA21 VIIRS data available from LAADS by the end of the year. We will post a product release notice on ladsweb (https://ladsweb.modaps.eosdis.nasa.gov/alerts-and-issues/) page once the data are available for download.

You can extract each layer by performing parameter subsetting using LAADS Post-Processing tools from LAADS “Find Data” Interface: https://ladsweb.modaps.eosdis.nasa.gov/search/ If you are new to ladsweb, you can consult the post processing tutorial at: https://ladsweb.modaps.eosdis.nasa.gov/learn/ho...
