This paper describes the GISS-E2.1 contribution to Coupled Model Intercomparison Project, Phase 6 (CMIP6). model version differs from predecessor (GISS-E2) chiefly due parameterization improvements atmospheric and ocean components, while keeping resolution same. skill when compared modern era climatologies is significantly higher than in previous versions. Additionally, updates forcings have a material impact on results. In particular, there been specific representations of modes variability...
Abstract The African continent continuously experiences extreme aerosol load conditions, during which the World Health Organization clean air standard of 10 μg/m 3 PM 2.5 mass is systematically exceeded. Africa holds world largest source desert dust emissions, undergoes strong industrial growth, and produces approximately a third Earth's biomass burning particles. Sub‐Saharan driven by agricultural practices, such as fields bushes in postharvest season for fertilization, land management,...
Abstract Simulations of the CMIP6 historical period 1850–2014, characterized by emergence anthropogenic climate drivers like greenhouse gases, are presented for different configurations NASA Goddard Institute Space Studies (GISS) Earth System ModelE2.1. The GISS‐E2.1 ensembles more sensitive to gas forcing than their CMIP5 predecessors (GISS‐E2) but warm less during recent decades due a reduction that is attributed greater longwave opacity in pre‐industrial simulations. This results an...
Abstract This paper presents the response to anthropogenic forcing in GISS‐E2.1 climate models for 21st century Shared Socioeconomic Pathways emission scenarios within Coupled Model Intercomparison Project Phase 6 (CMIP6). The experiments were performed using an updated and improved version of NASA Goddard Institute Space Studies (GISS) coupled general circulation model that includes two different versions atmospheric composition: A non‐interactive (NINT) with prescribed composition a tuned...
Abstract. We assessed the biomass burning (BB) smoke aerosol optical depth (AOD) simulations of 11 global models that participated in AeroCom phase III BB emission experiment. By comparing multi-model and satellite observations vicinity fires over 13 regions globally, we (1) assess model-simulated AOD performance as an indication source–strength, (2) identify where common dataset used by might underestimate or overestimate sources, (3) model diversity underlying causes much possible. Using...
Estimates of global thunderstorm activity have been made predominately by direct measurements lightning discharges around the globe, either optical from satellites, or using ground-based radio antennas. In this paper we propose a new methodology in which clusters are constructed based on strokes detected World Wide Lightning Location Network (WWLLN) very low frequency range. We find that even with detection efficiency scale, spatial and temporal distribution cells is well reproduced. This...
In August 2017, a smoke plume from wildfires in British Columbia and the Northwest Territories recirculated persisted over northern Canada for two weeks. We compared full-factorial set of NASA Goddard Institute Space Studies ModelE simulations to satellite retrievals aerosol optical depth carbon monoxide, finding that performance was dependent on model configuration, more so choice injection height approach, scheme biomass burning emissions estimates than horizontal winds nudging....
Abstract. The spatial distribution of aerosols and their chemical composition dictates whether have a cooling or warming effect on the climate system. Hence, properly modeling three-dimensional is crucial step for coherent simulations. Since surface measurement networks only give 2-D data, most satellites supply integrated column information, it thus important to integrate aircraft measurements in model evaluations. In this study, vertical secondary inorganic aerosol (i.e., sulfate,...
Abstract In 2019, Syria experienced its largest outbreak of fires since 2003, when fire occurrence began to be monitored via the MODIS satellite instruments. Here, we combine remotely sensed data on fire, local climatic conditions, and vegetation with spatial violence, territorial control, return internally displaced persons (IDPs) explore underlying causes Syria’s at sub-district, or ADM-3, level. We find evidence for a nuanced story: precipitation stabilization in Kurdish-controlled...
Abstract. Fires affect the composition of atmosphere and Earth's radiation balance by emitting a suite reactive gases particles. An interactive fire module in an Earth system model (ESM) allows us to study natural anthropogenic drivers, feedbacks, interactions open fires. To do so, we have developed pyrE, NASA GISS (Goddard Institute for Space Studies) emissions module. The pyrE is driven environmental variables like flammability cloud-to-ground lightning, calculated ModelE ESM,...
Abstract. We assessed the performance of 11 AeroCom models in simulating biomass burning (BB) smoke aerosol optical depth (AOD) vicinity fires over 13 regions globally. By comparing multi-model outputs and satellite observations, we aim to: (1) assess factors affecting model-simulated, BB AOD using a common emissions inventory, (2) identify where emission inventory might underestimate or overestimate sources, (3) anomalies that point to model-specific emission, dispersion, removal, issues....
