Also this year the fjords in western Norway are giving a spectacular show which can be enjoyed from the sky.
Sentinel-2 passing over Hardangerfjord at the end of May was catching the blooming of the Emiliania huxleyi algea which
is turing the water inside the fjord turquoise. This alga is harmless and is found in almost all ocean ecosystems from the equator to
sub-polar regions, with bools that are particularly visible in the Norwegian fjords.
Satellittdata is providing several tools and functionalities for users to views these kind of events.
The Norwegian Mapping Authority (Kartverket) has produced a cloud free national mosaic from Copernicus Sentinel-2 Level-2A data which has free access and is openly available. The dataset is found here. The mosaic is composed of Sentinel-2 data from June 30 to July 31, 2018. The mosaic consists of the frequency bands B2 to B8, B8A, B11, and B12. The data type is unsigned integer 16. Ancillary vector data is included yielding the dates for the individual tiles.
There have been problems with the Sentinel-3A SLSTR instrument in the period between 3rd and 12th of February 2020. Read more here: https://scihub.copernicus.eu/news/News00659
Since Saturday 11th January, all interfaces to colhub.met.no has been unavailable due to unforseen maintenance.We are looking into the problems and will solve them as fast as possible.
We apologize for any inconvenience this may have caused.
This interface is focusing on the possibilities opened by accessing data through OPeNDAP. OPeNDAP is a protocol that allows data streaming, in the sense that products are not required to be downloaded, but can be accessed without disk access. This implies that products are converted to NetCDF (SAFE is still available) which enables NBS to offer operations like subsetting and transformation (e.g. reformatting and reprojecting) more or less on the fly. Furthermore, it allows combination of products into spatial or temporal stacks of products for further processing.
Currently only Sentinel-2 is provided in this form, and NBS is working on Sentinel-1 access. Data are slightly postprocessed in NetCDF. All bands in Sentinel-2 are e.g. interpolated to the highest resolution, but using a lossless interpolation that allows users to access the original information.

This interface is the same as offered by e.g. SciHub. All data synchronised to the National Ground Segment are available as SAFE files in this interface.
