Due to a bug in the last software update, user credentials synchronization between colhub.met.no and colhub-archive.met.no was not possible since June 2022. Users who registered before that date can access colhub-archive with normality. However those colhub users who registered after June 2022 and new users will need to register at colhub-archive.met.no too.
We apologize for any inconvenience this may cause.
The service colhub and colhub-archive may experience some short interruption between 10:00 am and 14:00 am due to maintenance. We apologize for the possible inconvinience. After this maintenance, the user database will be updated and all colhub users will have access to the colhub-archive too.
From Sunday 18th December, the conversion process to NetCDF/CF for the integrated search interface stalled. We are looking into what causing the issue, and will let you know when the problem is solved.
Due to maintenance, data in the integrated portal in satellittdata.no, colhub.met.no, and colhub-archive.met.no will be unavailable between 22-23 November.
We apologize for any inconvenience this may cause.
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.
