# Aboveground Biomass Stock and Change 10 m

Chloris — version 5.0

## Description

This dataset quantifies aboveground biomass change (Mg/ha/y), aboveground biomass stock (Mg/ha), forest cover, forest area degradation, forest area gain, and forest area loss at 10 m spatial resolution, with global coverage annually from 2017 onwards. Data includes pixel-level variable uncertainties (± standard error).

## Variables

### aboveground_biomass_change
- **Type:** float32
- **Units:** Mg/ha/y
- **NoData:** 32767
Annual change in aboveground biomass stock variable. Data is generated using a Bayesian time series approach applied to aboveground biomass pixel values.

### aboveground_biomass_change_standard_error
- **Type:** float32
- **Units:** Mg/ha/y
- **NoData:** 65535
Standard error for aboveground biomass change variable.

### aboveground_biomass_stock
- **Type:** uint16
- **Units:** Mg/ha
- **NoData:** 65535
Total biomass stock of dry matter in live woody vegetation on a per hectare basis. Data is generated using machine learning models trained on field plot data and a variety of spaceborne remote sensing datasets.

### aboveground_biomass_stock_standard_error
- **Type:** uint16
- **Units:** Mg/ha
- **NoData:** 65535
Standard error for aboveground biomass stock variable.

### forest_area_degradation
- **Type:** float32
- **NoData:** 255
Indicates whether a forest pixel has lost aboveground biomass stock since the previous time point.

### forest_area_gain
- **Type:** float32
- **NoData:** 255
Indicates whether a non-forest pixel has become forest since the previous time point.

### forest_area_loss
- **Type:** float32
- **NoData:** 255
Indicates whether a pixel has become non-forest since the previous time point.

### forest_cover
- **Type:** float32
Indicates whether a pixel is forest.
