- Modeling global secondary organic aerosol formation and processing with the volatility basis set: Implications for anthropogenic secondary organic aerosol (2010, methodology): “Secondary organic gas‐ and aerosol‐phase dry deposition velocities are calculated by using a resistance‐in‐series model based on work by Koch et al. [1999]. The surface layer resistance for the gas phase depends on the same Henry’s law constant.”
- Calculation of radiative fluxes from the surface to top of atmosphere based on ISCCP and other global data sets: Refinements of the radiative transfer model and the input data (2004, methodology): “[23] The 03-Model also uses a new GISS global, 5 4 , monthly mean climatology of aerosol vertical profiles for the stratosphere and troposphere (including a separate dust component), composed of 18 different aerosol size and composition combinations to account for sulfates, sea salt, sulfuric acid, ”

- Climate forcings in Goddard Institute for Space Studies SI2000 simulations (2002, methodology): “The BC amount in the upper troposphere is about an order of magnitude greater than observed amounts [ Koch , 2001, Figure 5], although the amounts there are quite small.”
- Simulating the evolution of soot mixing state with a particle-resolved aerosol model (2008, unknown): “physical particle ratios, Kolodko and Sabelfeld [2003] gave relevant error estimates, and Debry et al.”
- Estimating Black Carbon Aging Time-Scales with a Particle-Resolved Aerosol Model (2009, methodology): “Many global models have simulated both (fresh) hydrophobic black carbon and (aged) hydrophilic black carbon, which can be considered a minimal representation of the black carbon mixing state (Cooke, Liousse, Cachier, & Feichter, 1999; Croft, Lohmann, & von Salzen, 2005; Koch, 2001; Lohmann, Feichter”
- Efficacy of climate forcings (2005, methodology): “13 W/m(2), Ea 100%, but the division of OC between OCI and OCB in our model is from aerosol transport model results [Koch, 2001] that assumed emission OC/BC ratios of 4 for fossil fuel (industrial) emissions and 7.”
- Simulation of direct radiative forcing of aerosols and their effects on East Asian climate using an interactive AGCM-aerosol coupled system (2012, methodology): “generally much farther than that of BC because of the strongly hydrophilic properties of OC. This implies that the spatial extent of the forcing due to OC is larger than that of BC. The simulated global annual mean of OC DRF at the TOA was -0.15 W m -2 , which agreed closely with the results of -0.1”
- Trends in aerosol radiative effects over Europe inferred from observed cloud cover, solar “dimming,” and solar “brightening” (2007, methodology): “The spatiotemporal distribution of tropospheric aerosols during 1983–1990 was instead determined by the aerosol transport model and emission scenarios used by Koch [2001] and Hansen et al. [2002].”
- Constraining the magnitude of the global dust cycle by minimizing the difference between a model and observations (2006, methodology): “To address this contribution by other species we use output from a multi-component aerosol model, where sulfate, sea salt, black and organic carbon are calculated (Koch, 2001; Koch et al., 2005; Koch and Hansen, 2005).”
- Earth's energy imbalance and implications (2011, background): “Aerosol forcing for 1880–1990, described by Hansen et al. (2007), is based on aerosol modeling (Koch, 2001) using aerosol emissions from fuel use statistics and including temporal changes in fossil fuel technologies (Novakov et al., 2003).”

- Aerosol Mixing State: Measurements, Modeling, and Impacts (2019, background): “…aerosol, the conversion of fresh (hydrophobic) to aged (hydrophilic) carbonaceous aerosol is often treated as an exponential decay process, with a constant half-life (Cooke & Wilson, 1996) ranging from 24 hr (Lauer et al., 2005) to approximately 40 hr (Lohmann et al., 1999; Koch, 2001).”
