NASA, ESA, JAXA Release Global View of COVID-19 Impacts
The dashboard will be released on Thursday, June 25 during a tri-agency media briefing. The briefing speakers are:
• Josef Aschbacher, director of ESA Earth Observation Programmes
• Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate
• Koji Terada, vice president and director general for the Space Technology Directorate at JAXA
• Shin-ichi Sobue, project manager for JAXA’s ALOS-2 mission
• Ken Jucks, program scientist for NASA’s OCO-2 and Aura missions
• Anca Anghelea, open data scientist, ESA Earth observation programmes

These maps compare the average nitrogen dioxide (NO2) concentrations for the time period from March 13 to April 13, 2020, to March-April 2019. Due to reduced industrial and social activity, the maps show a clear drop in atmospheric NO2 concentrations over Europe reaching over 50% over some of the main urban areas.

One type of agricultural productivity information that will be added to the dashboard in the weeks ahead comes from the Global Agriculture Monitoring (GLAM) System supported by NASA. This map shows the amount of surface moisture in soil across the United States from June 12-21. Red areas have dry soil conditions; green/blue areas are much wetter.

Using JAXA’s ALOS-2 and European Sentinel-1, cars in parking area near factories have been observed over time to monitor changes in car density. (Left) Red rectangle area shows parking area occupied by new cars at an automobile factory near Beijing airport in 2019 and 2020. In the period of the lockdown, the density of new cars has dropped significantly. (Right) A different example from Singapore port show the density of cars dropping from the end of April. The government decided to use that parking area for temporary accommodations for COVID-19 patients.

A NASA-NOAA satellite produces images of Earth at night that helps monitor light intensity to estimate energy use and economic activity. When San Francisco began to shelter in place in mid-March, city night lights detected from space did not change drastically. However, the University of California, San Francisco Medical Center brightened from January to April.

Nitrogen dioxide (NO2) abundances for March from the last four years and for 2020 from the OMI instrument on the NASA Aura satellite. The 2020 reductions in observed NO2 correspond with the reductions in fossil fuel emissions during that time frame in the New York City metropolitan area.

Changes in carbon dioxide (CO2) abundances from a model that is highly constrained by data from the NASA OCO-2 mission from the previous three years compared to 2020 for three separate times. These very small changes are expected. The timing of the low CO2 over Asia, then Europe, then the United States correspond with the reductions in fossil fuel burning from the slowdown in economies over these time frames.

Differences in CO2 concentrations between the lower and upper troposphere derived from the JAXA GOSAT satellite as derived from repeated focused observations over Beijing over the past four-plus years. These plots show that the lower troposphere abundances are lower than prior years through March but they appear to recover in April.

In Europe, the COVID19 outbreak severely restricted the movement of seasonal agricultural workers, which affected the highly labor-intensive harvesting of asparagus in Germany. Satellite observations allowed for monitoring continuously the cultivated white asparagus fields documenting a 20-30% lower area in March and April during the lockdown in Brandenburg.

The dashboard design and development evolved through the collaboration between the triagency engineering and science teams. A wide range of satellite Earth observation data were processed using established scientific protocols and innovative artificial intelligence methods to generate the dashboard information products. Cloud computing, datacubes and shared APIs were key enabling technologies.

COVID-19 Earth Observation Dashboard users can filter and select data from Countries and Indicators lists, the map (center), or from the table view. Spotlight Areas are marked on the map, with a number shown of how many indicators are available in each area. The right panel displays the indicator data and provides additional information.
