Using remote sensing for modeling carbon fluxes in forest ecosystems.
Neftaly | Using Remote Sensing for Modeling Carbon Fluxes in Forest Ecosystems
Quantifying the Pulse of the Forest—From Space
Forests play a central role in regulating the Earth’s carbon cycle, absorbing and emitting carbon through growth, decay, and disturbance. Understanding carbon fluxes—the exchange of carbon dioxide between forests and the atmosphere—is vital for climate change mitigation, carbon accounting, and sustainable land management. Neftaly uses cutting-edge remote sensing technologies to model and monitor carbon fluxes in forest ecosystems, offering scalable and science-based insights for carbon-focused strategies.
How Neftaly Models Carbon Fluxes with Remote Sensing
???? Satellite-Derived Vegetation and Biomass Data
Neftaly uses multispectral and radar satellite data (e.g. Sentinel-2, Landsat, GEDI LiDAR, and Sentinel-1) to estimate above-ground biomass, vegetation productivity, and structural changes over time—key inputs for calculating carbon uptake and loss.
???? Gross and Net Primary Productivity (GPP & NPP)
We analyze vegetation indices such as NDVI, EVI, and solar-induced chlorophyll fluorescence (SIF) to model GPP and NPP—quantifying how much carbon forests absorb during photosynthesis and how much is retained after plant respiration.
???? Disturbance and Emissions Mapping
Neftaly identifies carbon loss due to fires, logging, and degradation events using time-series change detection and burn severity indices—estimating emissions from disturbed forests.
???? Integration with Climate and Soil Data
Our models integrate remote sensing outputs with climatic variables, soil carbon data, and topography to enhance accuracy and simulate spatially explicit carbon fluxes at ecosystem and regional scales.
???? AI-Driven Modeling and Forecasting
Using machine learning and statistical modeling, Neftaly forecasts future carbon flux scenarios under different land use or climate conditions.

The effect of seasonal changes on soil carbon fluxes in boreal forests.
Neftaly Foundation: The Effect of Seasonal Changes on Soil Carbon Fluxes in Boreal Forests
Boreal forests, also known as taiga, cover vast areas across the Northern Hemisphere and serve as one of the largest terrestrial carbon sinks on Earth. A significant portion of this carbon is stored in soils, and its movement—known as soil carbon flux—is highly influenced by seasonal changes.
Understanding how seasonal cycles affect carbon release and storage in these ecosystems is essential for predicting their response to climate change and guiding global carbon management strategies.
What Is Soil Carbon Flux?
Soil carbon flux refers to the movement of carbon between the soil and the atmosphere. This includes:
- Carbon inputs (e.g., from decaying plant material and root exudates)
- Carbon outputs (e.g., carbon dioxide (CO₂) and methane (CH₄) emissions from microbial respiration)
Seasonal Impacts on Soil Carbon in Boreal Forests:
- Winter (Snow Cover and Frozen Soils)
- Low microbial activity due to frozen ground
- Soil respiration rates drop significantly
- Carbon accumulates as decomposition slows down
- Spring Thaw
- Rapid increase in microbial activity as soils warm
- Sudden release of stored carbon in the form of CO₂
- High flux rates due to decomposition of accumulated organic matter
- Summer (Active Growing Season)
- Increased root and microbial activity enhances both carbon input and output
- Moisture levels from snowmelt and rainfall promote carbon cycling
- Soil respiration peaks, contributing to higher carbon flux
- Autumn (Cooling and Leaf Fall)
- Decline in soil temperature slows microbial activity
- Leaf litter adds fresh organic material to the soil
- Carbon begins to accumulate again as respiration slows
Key Influencing Factors:
- Soil Temperature: A primary driver of microbial activity and decomposition
- Moisture Content: Affects oxygen availability and microbial processes
- Vegetation Cycle: Determines the timing and amount of organic input
Neftaly’s Commitment
At Neftaly Foundation, we are dedicated to supporting environmental education and sustainable forest management. Our work includes:
- Raising awareness about the role of boreal forests in climate regulation
- Supporting research on seasonal carbon dynamics and their climate feedbacks
- Promoting conservation and reforestation efforts in boreal regions
- Empowering communities to participate in monitoring forest health
Conclusion:
Seasonal changes in boreal forests create a dynamic pattern of soil carbon flux that significantly affects global carbon budgets. By understanding and protecting these systems, we help secure the planet’s future against the accelerating impacts of climate change.
