In order to help analyzing the IAGOS carbon monoxide (CO) observations and understanding the processes driving their evolutions, we provide ancillary parameters calculated with SOFT-IO (Sauvage et al., 2017; http://dx.doi.org/10.25326/2) along aircraft observations. CO contribution is defined as follow. CO mixing ratio is calculated for each IAGOS observations (every 0.5° in latitude or longitude at cruising altitude; every 10hPa during ascent or descent of the plane) and sorted by source origin (biomass burning and anthropogenic...

This dataset provides all vertical profiles over the airports visited by the IAGOS fleet. The profiles match the take-off and landing phases of the flights. The dataset includes values of all species measured by IAGOS instrumentation with a time acquisition resolution of 4 seconds as well as meteorological fields provided by the aircraft or the ECMWF.

The IAGOS Data Portal is the central service providing access to all the IAGOS datasets.

The standard IASI/Metop-A daily ammonia (NH3) total column dataset (ANNI-NH3-v2.2), described in [Van Damme et al.](https://www.atmos-meas-tech.net/10/4905/2017/) (2017) includes the results of a flexible and robust NH3 retrieval algorithm from measurements of the Infrared Atmospheric Sounding Interferometer (IASI). The method is based on the calculation of a spectral hyperspectral range index (HRI) and subsequent conversion to NH3 columns via a neural network. With this method: (1) complete temperature and humidity vertical profiles can be accounted for,...

The daily IASI/Metop-A carbon monoxide (CO) dataset is processed using the Fast Optimal Retrievals on Layers for IASI (FORLI) software [(Hurtmans et al., 2012)](https://doi.org/10.1016/j.jqsrt.2012.02.036). The IASI CO retrievals are performed in the 2143-2181.25 cm-1 spectral range using the optimal estimation method and tabulated absorption cross sections at various pressures and temperatures to speed up the radiative transfer calculation. A single a priori is used in the retrieval scheme. The temperature, pressure, humidity profiles and cloud...

The SEV06-CLD dataset provides cloud properties derived from the SEVIRI instrument series using algorithms that have been historically developped for the processing of MODIS data. SEV06-CLD uses MODIS-like algorithms for cloud optical and microphysical property retrievals, and a modified GOES-R Algorithm Working Group (AWG) algorithm for cloud-top temperature and pressure. Cloud masking is obtained from the Météo France Satellite Application Facility for supporting NoWCasting (SAFNWC) software package. The SEV06-CLD datasets share a common retrieval core...

This dataset provides climatologies for ozone and carbon monoxyde over a decade (2001-2010). Two types of climatologies are available: with 10 fixed pressure levels (from 288 hPa to 186 hPa) or with 4 dynamic pressure levels (lower stratosphere, upper statisphere, tropopause, upper troposphere).

The IASI/Metop-B daily formic acid (HCOOH) total column dataset, described in [Pommier et al.](https://www.atmos-chem-phys.net/16/8963/2016/) (2016), relies on a fast approach based on conversion factors between brightness temperature differences and representative retrieved total columns over seven regions: Northern Africa, southern Africa, Amazonia, Atlantic, Australia, Pacific, and Russia. The dependence of the measured HCOOH signal on the thermal contrast is taken into account in the conversion method. The dataset is available on a global scale from March...

The climatological vertical stratification of ozone (O3) and carbon monoxide (CO) within the planetary boundary layer (PBL) and at the interface with free troposphere (FT) was derived using all IAGOS (In-service Aircraft for a Global Observing System) and WOUDC (World Ozone and Ultraviolet Radiation Data Centre) vertical profiles available at northern mid-latitudes (25°N-60°N) between August 1994 and December 2016 (Petetin et al., 2018). The methodology is the following : 1) All profiles with a surface-based...

The number concentration of cloud particles is a key quantity for understanding aerosol-cloud interactions and describing clouds in climate and numerical weather prediction models. In contrast with recent advances for liquid clouds, few observational constraints exist on the ice crystal number concentration (Ni). This dataset provides a new satellite product of Ni obtained from combined lidar-radar measurements from the A-Train.
