NAMMA CARBON MONOXIDE BY ATTENUATED LASER TRANSMISSION (COBALT) V1
The NAMMA Carbon mOnoxide By Attenuated Laser Transmission (COBALT) dataset includes measurements of the carbon monoxide mixing ratio and derived carbon monoxide mixing ratio profiles in the upper troposphere/lower stratosphere using an in-situ laser absorption spectrometer. These data files were generated during support of the NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign, a field research investigation sponsored by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA). This mission was based in the Cape Verde Islands, 350 miles off the coast of Senegal in west Africa. Commencing in August 2006, NASA scientists employed surface observation networks and aircraft to characterize the evolution and structure of African Easterly Waves (AEWs) and Mesoscale Convective Systems over continental western Africa, and their associated impacts on regional water and energy budgets.

1/8˚ resoluton MOM6-COBALT daily physical and biogeochemical diagnostics for 2014
<p>The files in this dataset contain daily mean chlorophyll (µg/kg), pH, nitrate (mol/kg), dissolved oxygen (mol/kg), potential temperature (˚C) and salinity model outputs for 2014 for the region between 20-55˚N, 135-111˚W. Data was extracted from a global grid run with coupled ocean-ice model configured using the Modular Ocean Model 6 (MOM6, <a href="https://github.com/NOAA-GFDL/MOM6">https://github.com/NOAA-GFDL/MOM6</a> ) and Sea Ice Simulator (SIS2) developed at the NOAA Geophysical Fluid Dynamics Laboratory (Adcroft et al., 2019). The horizontal resolution of the grid is 1/8˚, which is considered eddying and no eddy parameterization was included. Vertically, the model uses 75 hybrid vertical-sigma2 layer coordinates that is remapped onto 35 World Ocean Atlas/Coupled Model Intercomparison Project standard depth levels. The atmospheric forcing was derived from the Japanese 55-year Reanalysis version 1.5 (JRA55 1.5, <a href="https://jra.kishou.go.jp/JRA-55/index_en.html#jra-55">https://jra.kishou.go.jp/JRA-55/index_en.html#jra-55</a>). The model is driven by river freshwater runoff from a monthly climatology derived from Dai and Trenberth (2002) and Dai et al. (2009), which can be assessed at <a href="https://rda.ucar.edu/datasets/ds551.0/">https://rda.ucar.edu/datasets/ds551.0/</a>. A remapping scheme was used to add freshwater into the appropriate coastal grid cells near the river mouths. The biogeochemical model used was the Carbon, Ocean Biogeochemistry and Lower Trophics (COBALTv2, Stock et al., 2020), which uses 33 tracers for representation of coupled elemental cycles of carbon, nitrogen, phosphorus, iron, silicon, alkalinity, oxygen and lithogenic matter and associated plankton food web dynamics. More details about the model setup are described in Liu et al. (2019) and Liu et al. (2021).

Cobalt(III)-Catalyzed Diastereo- and Enantioselective Three-Component C–H Functionalization
<p>Catalytic enantioselective C–H functionalization has recently become a tool for the creation of stereogenic centers. The steep increase in molecular complexity of multicomponent reactions matches very well with asymmetric C–H functionalizations, but the realization of such processes remains a large challenge. We describe a diastereoselective and highly enantioselective three-component C–H functionalization catalyzed by an earth-abundant Co(III) complex equipped with a chiral cyclopentadienyl ligand (Cp<sup>x</sup>). The transformation provides a rapid access to substituted β-hydroxyketones using three readily accessible starting materials. The outlined reactivity of Cp<sup>x</sup>Co(III) catalysis shows a higher and exploitable propensity for selective additions across carbonyls in contrast to the chemistry of Rh(III).</p>
Cobalt(III)-Catalyzed Enantioselective Intermolecular Carboamination by C−H Functionalization
<p>High-valent cyclopentadienyl cobalt catalysis is a versatile tool for sustainable C−H bond functionalizations. To harness the full potential of this strategy, control of the stereoselectivity of these processes is necessary. Herein, we report highly enantioselective intermolecular carboaminations of alkenes through C−H activation of <em>N</em>-phenoxyamides catalyzed by Co<sup>III</sup>-complexes equipped with chiral cyclopentadienyl (Cp<sup>x</sup>) ligands. The method converts widely available acrylates as well as bicyclic olefins into attractive enantioenriched isotyrosine derivatives as well as elaborated amino-substituted bicyclic scaffolds under very mild conditions. The outlined reactivity is unique to the Cp<sup>x</sup>Co<sup>III</sup> complexes and is complementary to the reactivity of 4d- and 5d- precious-metal catalysts.</p>
