Hello, Yes. That is definitely a mistake in the description for this variable. Yes. That is how you can convert the mixing ratio to ppm. I am not certain about the accuracy of the mixing ratios in those regions since there are limited validation datasets at those locations. Before drawing conclusion...

Hello, These are both the CO2 upper troposphere volume mixing ratios. Since AIRS is in a Sun synchronous orbit it crosses the equator at ~ 1:30 PM and 1:30 AM local time every orbit. The variable includes both orbit passes. The first orbit pass is ~ 1:30 PM ("daytime" at the equator) and t...

The filename "AIRS.2023.09.18.051.L1B.SUBIBRAD.v5.0.25.0.G23261111848.hdf" is just a file that has been subsetted from the following dataset: AIRS project (2007), AIRS/Aqua L1B Infrared (IR) geolocated and calibrated radiances V005, Greenbelt, MD, USA, Goddard Earth Sciences Data and Infor...

Are you interested in using an AIRS Level 2 or Level 3 surface relative humidity? The Level 2 variable is called "RelHumSurf" and the Level 3 variable is called "RelHumSurf_A" or "RelHumSurf_D" for the ascending or descending parts of the orbit. More information about t...

You can find a more detailed description of how the dust_score is calculated in DeSouza-Machado et al. (2010). Although DeSouza-Machado et al. (2010) say that there are very few false positives over tropical and mid-latitude oceans when the dust_score is above 380, you can perform your own assessmen...

We recently received a new dataset at the GES DISC that includes data from the following platform and instruments that are not in the GCMD database. Platforms: KOMPSAT-5 (Korea Multi-Purpose Satellite-5) / Arirang-5 https://directory.eoportal.org/web/eoportal/satellite-missions/k/kompsat-5 PAZ SAR s...

The OCO-2 version 9r Lite files will not be processed beyond January 22, 2020. Lite files are produced using the retrospectively-processed data and are typically available no earlier than a month after the observation time. Following the OCO Team efforts to improve the pending release, there is a de...
