Data sets

TCCON data from Sodankylä (FI), Release GGG2014.R0 R. Kivi, P. Heikkinen, and E. Kyrö

MUSICA IASI full retrieval product standard output (processing version 3.2.1) Matthias Schneider, Benjamin Ertl, and Christopher Diekmann

The ground-based MUSICA dataset: Tropospheric water vapour isotopologues (H216O, H218O and HD16O) as obtained from NDACC/FTIR solar absorption spectra Sabine Barthlott, Matthias Schneider, Frank Hase, Thomas Blumenstock, Gizaw Mengistu Tsidu, Michel Grutter de la Mora, Kim Strong, Justus Notholt, Emmanuel Mahieu, Nicholas Jones, and Dan Smale

Short summary
We compare column-averaged dry-air mole fractions of water vapor (XH2O) retrievals from the COllaborative Carbon Column Observing Network (COCCON) with two co-located ground-based spectrometers as references at two boreal sites. Our study supports the assumption that COCCON also delivers a well-characterized XH2O data product. This is the first published study applying COCCON for MUSICA IASI and TROPOMI validation.
