Service Line 2

Rewetting only counts as a success once it can be quantified.

For funding applications, certification and monitoring, rewetting needs a calibrated measurement — not a model assumption. NordiQ delivers it from satellite data, matched against real gauge readings.

The Problem

No measurement, no proof

Peatland protection and rewetting projects need a robust, area-specific proof for funding, CO₂ certification and reporting obligations — not just literature values per peat type.

💧

Groundwater level is the key metric

The depth of the dry front determines a peatland's CO₂ balance — but area-wide on-site measurement is expensive and only point-based.

📉

Modeled instead of measured values

Many reports calculate with IPCC standard factors per peat-type class — without site-specific evidence of actual development.

🔁

Monitoring over years

Rewetting works slowly. Without a continuous time series, a project's success is hard to demonstrate objectively.

Methodology

From satellite signal to calibrated measurement

Four layers, combined into an area-wide, satellite-calibrated dry-front depth value per area and year.

1

Groundwater-level proxy from Sentinel-1 SAR

Backscatter anomalies as an indicator of the shifting drying front — area-wide, cloud-independent, monthly time series possible.

2

Vegetation stress via NDMI (Sentinel-2)

Moisture index as an independent validation layer at pixel level.

3

Climatic context via ERA5-Land

Water balance and evapotranspiration estimation as a background correction.

4

Calibration with gauge data

Converting the satellite signal into a quantitative dry-front depth (cm) — the input for CO₂ flux estimates under IPCC emission factors.

Target Groups

Who this is for

Municipalities & water/soil associations
Peatland protection and rewetting projects
CO₂ certifiers and offset projects

For regulatory accreditation, NordiQ partners with providers of ground-based point measurements — the satellite proxy and the MRV report come from NordiQ, on-site certification from the partner. One report, one point of contact, two independent measurement layers.

Cost depends on area size and desired cadence — we calculate it together based on your project.
