+# CarbonGlobe: A Global-Scale, Multi-Decade Dataset and Benchmark for Carbon Forecasting in Forest Ecosystems
+
+**CarbonGlobe** is a global-scale, multi-decade, machine-learning-ready dataset and benchmark for forecasting carbon dynamics in forest ecosystems. The dataset provides harmonized environmental drivers and carbon-related ecosystem outputs simulated by the **Ecosystem Demography model version 3 (ED v3)**, enabling the development, evaluation, and comparison of deep learning models for global forest carbon forecasting.
+
+CarbonGlobe was accepted to the **NeurIPS 2025 Datasets & Benchmarks Track**. 
+
+**Project page**: https://github.com/zhwang0/carbon-globe
+
+## Dataset Description
+
+Forest ecosystems play a central role in the global carbon cycle, but forecasting their long-term dynamics remains challenging because process-based ecosystem models are computationally expensive and difficult to scale across large spatial domains and many scenarios.
+
+CarbonGlobe addresses this challenge by providing a reproducible benchmark for learning from process-based ecosystem simulations. It bridges **Earth system science** and **machine learning** by transforming global ED v3 simulations and associated environmental drivers into a standardized dataset for carbon forecasting.
+
+The dataset is designed to support the development of machine learning emulators and forecasting models that can predict multivariate ecosystem trajectories under diverse climate, regional, and ecological conditions.
+
+## Dataset Summary
+
+CarbonGlobe includes:
+
+- **Global 0.5° spatial coverage**, with approximately 70,000 grid cells
+- **Multi-decade temporal coverage**, spanning more than 40 years from 1980 to 2020
+- **Monthly time-series data** for long-term ecosystem forecasting
+- **100+ environmental input variables** from meteorological, atmospheric, soil, and vegetation-related sources
+- **ED v3-simulated ecosystem output variables**, including carbon stocks, vegetation structure, and ecosystem fluxes
+- **ML-ready samples** for training and evaluating time-series forecasting models
+- **Scenario-based evaluation protocols** for assessing model robustness under climate, forest-age, and regional domain shifts
+
+## Supported Tasks
+
+CarbonGlobe supports the following machine learning tasks:
+
+- Multivariate time-series forecasting
+- Forest carbon forecasting
+- Ecosystem model emulation
+- Long-horizon sequence prediction
+- Spatiotemporal environmental modeling
+- Domain generalization across climate zones, regions, and forest conditions
+- Benchmarking deep learning models for Earth system applications
+
+## Dataset Structure
+
+Each sample contains environmental input drivers, ED-simulated target variables, temporal information, and geographic/ecological metadata.
+
+Input variables include environmental drivers such as:
+
+```text
+Meteorological variables, atmospheric CO2, soil properties, vegetation-related variables, and other environmental covariates.
+```
+
+Target variables include ED v3-simulated ecosystem states and fluxes, such as:
+
+```text
+Vegetation height, soil carbon (SC), above-ground biomass (AGB), leaf area index (LAI), gross primary productivity (GPP), net primary productivity (NPP), heterotrophic respiration (RH).
+```
+
+
+## Data Sources
+
+CarbonGlobe is constructed from harmonized environmental input variables and outputs simulated by the **Ecosystem Demography model version 3 (ED v3)**.
+
+The dataset is intended to provide a standardized machine learning benchmark for carbon forecasting in forest ecosystems. It enables users to train data-driven forecasting models using the same input-output structure as process-based ecosystem simulations, while supporting controlled evaluation across ecological and geographic domains.
+
+## Dataset Splits
+
+CarbonGlobe supports multiple evaluation settings for both standard forecasting and domain generalization.
+
+Recommended split types include:
+
+- **Random split**: standard train/validation/test evaluation across global samples
+- **Regional split**: evaluation across geographic regions
+- **Climate-zone split**: evaluation across Köppen–Geiger climate domains
+- **Forest-age or ecosystem-condition split**: evaluation across different ecosystem development stages
+- **Temporal forecasting split**: training on historical sequences and evaluating long-horizon future prediction
+
+Please refer to the accompanying benchmark code for the exact split definitions and evaluation protocol.
+
+## Metadata
+
+Each sample may include metadata such as:
+
+- Geographic coordinates
+- Grid identifier
+- Köppen–Geiger climate zone
+- Dominant forest type
+- Monthly time index
+- Train/validation/test split indicator
+
+These metadata enable controlled evaluation of model generalization across environmental domains, including:
+
+- Tropical to temperate transfer
+- Humid to arid climate transfer
+- Cross-region forecasting
+- Cross-forest-type forecasting
+- Generalization across forest structural or developmental conditions
+
+## Benchmark Models
+
+CarbonGlobe includes benchmark results from representative forecasting models across multiple modeling paradigms.
+
+Evaluated models include:
+
+- **LSTM**
+- **LSTNet**
+- **DeepED**, a physics-guided deep learning emulator for ecosystem dynamics
+- **Transformer**
+- **Informer**
+- **Crossformer**
+- **TimeXer**
+- **DLinear**
+
+These models are evaluated for multivariate ecosystem trajectory prediction under both standard and domain-shift settings.
+
+## Evaluation
+
+CarbonGlobe is designed for multivariate, long-horizon ecosystem forecasting. Recommended evaluation metrics include:
+
+- Root mean squared error (RMSE)
+- Mean absolute error (MAE)
+- Delta error
+- Cumulative error
+
+In addition to pointwise prediction accuracy, users are encouraged to report trajectory-level metrics that evaluate whether models preserve long-term ecosystem dynamics, temporal changes, and accumulated carbon-cycle behavior.
+
+## Intended Uses
+
+CarbonGlobe is intended for research and benchmarking in:
+
+- Forest carbon forecasting
+- Ecosystem model emulation
+- Climate impact assessment
+- Long-term ecological forecasting
+- Earth system machine learning
+- Development and evaluation of deep learning models for environmental time series
+- Benchmarking generalization under climate, regional, and ecological domain shifts
+- Scalable approximation of process-based ecosystem model outputs
+
+## Ethical and Environmental Considerations
+
+CarbonGlobe does not contain personal or sensitive human information. The dataset is based on environmental drivers and process-based ecosystem model simulations.
+
+Potential positive impacts include improved accessibility of global carbon forecasting benchmarks, reduced computational barriers for ecosystem model emulation, and stronger collaboration between machine learning and Earth system science communities.
+
+Potential risks include over-interpreting model predictions as direct real-world forecasts, using outputs without accounting for uncertainty, or applying benchmark-trained models to policy-sensitive decisions without additional validation.
+

+# CarbonGlobe Dataset
+Our dataset, CarbonGlobe, is accepted to NeurIPS 2025 Dataset and Benchmark track.
+
+## Overview
+The CarbonGlobe dataset is designed for forest carbon dynamics monitoring and forecasting. It includes various ecological and environmental variables collected over a 40-year temporal range and a global spatial scale. This ML-ready dataset integrates over 100 variables from heterogeneous sources.
+
+## Data Structure
+Main Directory
+data_global/: Contains input features and output data for different forest ages.
+	glob_X_fea.npy: Input features.
+	glob_Y001.npy to glob_Y500.npy: Output data at different forest ages.
+data_stats/: Contains statistical information.
+	data_stats.npz: Mean and standard deviation information.
+	age_triplet.npz: Age triplet data.
+	mask2d.npy: Mask data converting 1d raw data to 2d at global scale.
+insitu_data/: Contains in-situ observations from the ABoVE GPP dataset
+	lat....csv: contains the GPP observations in this location.
+	lat_lon_age_weights.csv: weighted sum all ages from 1 to 500 to recover the obs.
+train.csv: Indices for training samples.
+val.csv: Indices for validation samples.
+test.csv: Indices for test samples.
+readme.txt: This file.
+
+## Code Repository
+The code used for developing the dataset is available on GitHub: https://github.com/zhwang0/carbon-globe
