Bring your processed flux data.
FluxGapFill maps the rest.
Start from computed fluxes or half-hourly/hourly environmental data—not raw high-frequency sonic/IRGA signals. EddyPro, Campbell TOA5, AmeriFlux/FLUXNET-style files, generic delimited files and Excel workbooks can enter the same transparent project schema.
1. Project data
Primary processed flux/environmental file plus optional supplemental weather data.
2. Project policy
Time handling is explicit because logger conventions differ.
Verify before processing
FluxGapFill proposes mappings and units but does not silently assume unknown fields. Correct any suggestion here before loading the project.
Primary file
Not inspected
| Role | Source column | Unit | Detection |
|---|---|---|---|
| Inspect a primary file first. | |||
Supplemental file
Optional
| Role | Source column | Unit | Detection |
|---|---|---|---|
| No supplemental file selected. | |||
Input preview
First records only. Preview does not alter the file.
| Inspect a file to preview it. |
Quality, completeness and gap structure
Standardized midpoint grid after mapping, unit normalization, QC screening and optional supplemental alignment.
Measured fluxes
Downsampled only for visualization; calculations use every record.
Project details
Predictor availability
Variables visible to current/future analysis modules.
| Variable | Complete | N |
|---|
Use what is ready. Add data where needed. Skip the rest.
Each analysis module checks required variables independently, so missing footprint or carbon information never blocks gap filling or ET work.
Optional site information
Needed by selected advanced modules; leave blank if not applicable.
How optional modules behave
Validate models on realistic calendar outages
Existing Phase-1 package retains the validated MDS/RF/XGBoost workflow while the universal project foundation is introduced.
Validation design
Quick mode uses one window per duration. Increase windows for a stronger benchmark.
Adaptive fill policy
Use the best validated method by gap duration or force one method.

Selected model by duration
Gap-filled fluxes with provenance
Measured observations remain unchanged; reconstructed values retain method labels and validation diagnostics.
Final LE and H
Method provenance
Daily ET from final LE
Temperature-dependent latent heat of vaporization.
