Beijing Urban Heat and CO2 Flux Observations with SUEWS Model Runs

Observations from May 2010 to July 2012 at the IAP tower in Beijing include radiation fluxes, turbulent fluxes (CO2, latent and sensible heat) for 2016, and meteorological data. This dataset supports the manuscript 'Simulating heat and CO2 fluxes in Beijing using SUEWS V2020b' and contains processed observations, model runs, and Python code for quality control and gap-filling. The data is intended for validating and applying the Surface Urban Energy and Water balance Scheme (SUEWS) model to urban environments.

Use Cases

• [Validating urban land surface models] based on [observed turbulent and radiation fluxes from an eddy covariance tower]
• [Analyzing seasonal and diurnal cycles of CO2 exchange] based on [mean diurnal seasonal cycle data for Fc]
• [Assessing data quality control methods for eddy covariance] based on [provided Python scripts for stationarity and friction velocity filtering]
• [Parameterizing vegetation phenology in models] based on [Leaf Area Index (LAI) data derived from Landsat 7 ETM+]
• [Conducting sensitivity analysis of model outputs] based on [provided SUEWS model runs with adjusted external parameters]

Strengths

• Includes both raw and quality-controlled flux observations for 2016, enabling analysis of data processing impacts.
• Covers multiple years (2010-2012) of meteorological observations at different heights on the IAP tower.
• Provides accompanying Python code for reproducible data processing, including gap-filling and quality control routines.
• Dataset was updated in June 2023 with higher-resolution LAI data derived from Landsat 7 ETM+.

Limitations

• Key metadata such as row counts, file sizes, and specific column names are not provided in any source.
• The temporal coverage is fragmented across different variables (e.g., radiation 2010-2011, turbulent fluxes 2016).
• The dataset's last update date is inconsistently reported, with one source noting a version from June 2023 while others list 'None'.

Provenance

Source

Observations were collected at the IAP tower in Beijing, China.

Collection Method

Radiation and turbulent flux data were likely obtained via instrument measurements, with turbulent fluxes specifically gathered using the eddy covariance technique. LAI data was derived from Landsat 7 ETM+ imagery.

Time Range

May 2010 to 2012 for meteorological data, with specific flux observations for 2016.

Freshness

Version 2 was created on June 9, 2023, according to one source.

Geography

Beijing, China, specifically the IAP tower location.
