Summary
Forest fires release significant greenhouse gases. This study used satellite data to monitor burned areas and quantify carbon dioxide emissions in Mount Arjuno, Indonesia, aiding environmental impact assessment.
Area of Science:
- Environmental Science
- Remote Sensing
- Climate Change
Background:
- Forest fires are a major source of greenhouse gas emissions, primarily carbon dioxide.
- Rising global temperatures increase the frequency and intensity of forest fire events.
- Rapid quantification of emissions is crucial for assessing environmental impacts.
Purpose of the Study:
- To apply Google Earth Engine for monitoring forest fire-affected areas.
- To quantify carbon dioxide emissions from forest fires in Mount Arjuno, Indonesia.
- To analyze the relationship between emissions, local temperature, and atmospheric CO concentrations.
Main Methods:
- Utilized Landsat-8 and Sentinel-2 satellite imageries for burned area monitoring.
- Employed Google Earth Engine platform for data processing and analysis.
- Retrieved CO total column mixing ratio from Sentinel-5P TROPOMI.
Main Results:
- Mapped burned areas in Mount Arjuno, Indonesia, from 2016-2019.
- Estimated carbon dioxide emissions at 2.5 × 10³ tCO₂/km² burned area.
- Observed higher CO₂ emissions correlated with increased local surface temperature and atmospheric CO.
Conclusions:
- Google Earth Engine is effective for monitoring forest fire impacts.
- Forest fires in the region significantly contribute to carbon dioxide emissions.
- Environmental monitoring using satellite data is vital for climate change studies.

01:05Estimation of the Physical Quantities
6.5K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
