IAGOS ancillary data (L4) - CO contributions to the aircraft measurements

Bastien Sauvage, Philippe Nédélec & Damien Boulanger
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...

Daily IASI/Metop-A ULB-LATMOS carbon monoxide (CO) L2 product (total column)

Cathy Clerbaux
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...

Reanalyzed daily IASI/Metop-A ULB-LATMOS ammonia (NH3) L2 product (total column)

Lieven Clarisse, Martin Van Damme & Pierre-François Coheur
The reanalyzed IASI/Metop-A daily ammonia (NH3) total column dataset (ANNI-NH3-v2.2R-I), 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,...

SOFT-IO: SOft attribution using FlexparT and carbon monoxide emission inventories for In-situ Observation database

B. Sauvage, A. Auby & A. Fontaine
SOFT-IO is a tool based on the FLEXPART particle dispersion model (Stohl et al., 2005) coupled on emission inventories provided in the scientific community. It has been developed to quantify source/receptor links for atmospheric trace gases. SOFT-IO simulates the contributions of anthropogenic and biomass burning emissions from the ECCAD emission inventory database for all locations and times corresponding to the measured carbon monoxide mixing ratio along each flight measurements. The main goal is to supply...

Hervé Petetin, Bastien Sauvage, Philippe Nédélec & Damien Boulanger
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...

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).

Ice crystal number concentration from satellite lidar-radar observations (DARDAR-Nice)

Odran Sourdeval, Edward Gryspeerdt, Martina Krämer, Tom Goren, Julien Delanoë, Armin Afchine, Friederike Hemmer & Johannes Quaas
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.

The IASI/Metop-A 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 October...

Daily Accumulated Surface Rainfall MT_L4_TAPEER-BRAIN Product

Rémy Roca
The TAPEER-BRAIN algorithm combines microwave and infrared observations to provide precipitation estimates and associated errors bars at the one-degree/one-day accumulated scale. It relies on rain detection from LEO microwave imagers (TRMM/TMI, F15/SSMI, F16/SSMIS, F17/SSMIS, F18/SSMIS, GCOMW1/AMSR2) and sounders (Megha-Tropiques/SAPHIR) as well as instantaneous precipitation retrievals from LEO microwave imagers using the BRAIN algorithm (Viltard et al, 2006). Those detections and rain rates estimates are then merged with full space/time resolution data from the thermal window...

SEV06-CLD : A MODIS-like SEVIRI cloud products dataset

G. Wind, S. Platnick, J. Riedi, A. Heidinger, S. Ackerman & B. Baum
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...
