New research investigates global carbon cycle from phytoplankton satellite imagery

A recent study has produced a 20-year time series of primary production by marine phytoplankton, one of the largest fluxes of carbon on our planet. Studying phytoplankton primary production is important because it provides useful information about ocean biology, climate, and global carbon cycle. Observing primary production over long-time scales or quantifying its small variations can help the scientific community to determine carbon dioxide concentrations, as well as the effect of climate variability on these processes.

Participants will learn which pollutants can be measured from space, how satellites make these measurements, the do’s and don’ts in interpreting satellite data, and how to download and create your own visualizations.
Learning Objectives
By the end of this training, attendees will be able to:
  • List the pollutants that can be observed by NASA satellites
  • Find and download imagery for NO2 and aerosols/particles
  • Describe the capabilities and limitations of NASA NO2 and aerosol measurements

NASA and NOAA satellites monitor deadly Guatemala volcano eruption

Satellites from NASA and the US National Oceanic and Atmospheric Administration (NOAA) are monitoring the eruption of Volcan de Fuego (Volcano of Fire) in Guatemala that has killed at least 69 people since it started erupting on 3 June 2018.

The Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the joint NOAA/NASA Suomi National Polar-orbiting Partnership (Suomi-NPP) satellite captured an imagery) of the eruption and resulting ash plume emitted by the volcano.

Detecting forest fires with satellites (MODIS and VIIRS)

Since several years ago, satellites have been used to detect fires. The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites has been used to scan the Earth’s surface for fires on a daily basis for almost 15 years. Since 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi NPP satellite has contributed to this effort by producing higher resolution images of the Earth’s surface.

NASA: A Look Back at a Decade of Fires

NASA's latest Earth-observing satellite, the NPOESS Preparatory Project (NPP), is scheduled to launch from Vandenberg Air Force Base on Oct. 28 to extend key environmental data records established by an earlier generation of NASA satellites. To mark the launch, they are looking back at one of the scientific legacies NPP will build upon: the global fire data record. An instrument on NPP called the Visible Infrared Imager Radiometer Suite (VIIRS) will extend this decades-long record into the future.
