Dataset description

QDOAS is a cross-platform application based on the long experience of BIRA-IASB (Royal Belgian Institute for Space Aeronomy) in the development and improvement of algorithms for the retrieval of trace gases from UV-Visible spectral measurements (satellite, ground-based, mobile or aircraft-based instruments) using the Differential Optical Absorption Spectroscopy (DOAS) technique. This software evolves along with the measurement techniques in DOAS. It has been extensively validated in different intercomparison campaigns. The friendly user interface, flexibility and the robustness of the algorithms largely contribute to QDOAS' success in the world. QDOAS packages for Windows, Linux and macOS are available from conda-forge.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

api.store is built and operated by Apitalks s.r.o. Company details and a direct contact path are linked in the footer for vendor checks and procurement review.
Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
