Fabio, This issue is related to the change in filename for the MLAC data with the recent reprocessing. Unfortunately, there is no longer a direct link (by way of the filename) between the L1 files and the L2 files and the old browser was expecting that, at least for the data ordering. Unfortunately,...

Make sure you are using the same ancillary inputs that were used in the OBPG processing. With NRT files, the OBPG processes with the best available at the time of processing. If you process a file later, is it possible - actually quite likely - that the ancillary files obtained via getanc will not b...

The data are stored as signed short integers, so, if you are seeing floating point values, the function you used to read the PIC product applied the scale and offset values. The scale_factor and add_offset values are applied to the data using this simple equation: geophysical_value = scale_factor * ...

The issue stems from how the filenames are defined, and for SeaWiFS this most impacts the MLAC data. MLAC are merged files with all of the HRPT (direct broadcast) and on board recorded LAC (local area coverage) data. When the MLAC files were developed, we needed a way to ensure we didn't have duplic...

The binned file format is not a raster format and cannot be read by GIS tools...it's also not a 3D product, rather it is essentially spreadsheet... it's complicated ;) . However, the mapped product that we distribute (which are generate from the binned product) are 2D rasters that can be loaded into...

The cause has been identified and corrected. Reprocessed imagery should be available in Worldview soon.

I did not mean to suggest that the sensor degradation was the sole reason for differences you see between Hawkeye and MODIS-Aqua. In fact, most of the degradation occurred during the extended commissioning phase. While the instrument likely continues to degrade, the rate of change over time is much ...

Negative Rrs retrievals is the result of an atmospheric correction issue, most often an over estimate of the atmospheric aerosol contribution. Negative TOA reflectance, well that's just bad data. It should not be a common situation. If you are finding it to be more than an extremely rare condition, ...

Bruce, I don't have an answer for you except to say that getting the binner to be happy with the insane number of products that OCI will produce is actively being worked :). I do know that there was a memory issue that was identified and resolved, perhaps that was affecting your processing. This and...
