What were the highlights of her more recent work (between 2013-2018)?

  • Aerosol (37.04%)
  • Dry season (11.11%)
  • Atmospheric sciences (40.74%)

In recent papers she was focusing on the following fields of study:

Her primary areas of investigation include Aerosol, Dry season, Atmospheric sciences, Precipitation and Air quality index. Her work in Aerosol addresses issues such as Environmental chemistry, which are connected to fields such as Plume. Her Dry season research spans across into fields like Smoke, Amazonian, Atmospheric measurements, Lidar and Unified Model.

Her work deals with themes such as Effects of high altitude on humans, Altitude, Haze and AERONET, which intersect with Atmospheric sciences. Her work on Global Precipitation Measurement as part of her general Precipitation study is frequently connected to Range, thereby bridging the divide between different branches of science. Her Convection study improves the overall literature in Meteorology.

Between 2013 and 2018, her most popular works were:

  • ACRIDICON–CHUVA Campaign: Studying Tropical Deep Convective Clouds and Precipitation over Amazonia Using the New German Research Aircraft HALO (82 citations)
  • Ground-based aerosol characterization during the South American Biomass Burning Analysis (SAMBBA) field experiment (63 citations)
  • Characterising Brazilian biomass burning emissions using WRF-Chem with MOSAIC sectional aerosol (36 citations)

In her most recent research, the most cited papers focused on:

  • Meteorology
  • Thermodynamics
  • Atmosphere of Earth

The scientist’s investigation covers issues in Aerosol, Precipitation, Dry season, Convection and Range. Karla M. Longo integrates Aerosol with Volatilisation in her study. Volatilisation is integrated with Environmental chemistry, Pollution, Plume, Mixing ratio and Aerosol mass spectrometry in her study.

In her research, she undertakes multidisciplinary study on Environmental chemistry and Field experiment. Her Convection research entails a greater understanding of Meteorology. Her Effects of high altitude on humans research incorporates elements of Single-scattering albedo, Atmospheric sciences, Weather Research and Forecasting Model, AERONET and Altitude.
