Current projects for PhD
[1] Monitoring and forecasting the forest change in Haiti and Dominican Republic
- Use all available Landsat data to detect the land cover change in Haiti and Dominican Republic.
- Generate the annual land cover data to analyze the primary and secondary forest change.
- Simulating the historical and future land cover change with land change model.
[2] Continuous estimation of impervious surface percentage (ISP)
- Employ the very-high-resolution land cover data to create the ISP map.
- Train the convolution neural network with the ISP map and CCDC (Continuous Change Detection and Classification) algorithm outputs.
- Generate the 30-meter resolution ISP dataset over an extensive scale.
Previous projects
[3] Global seamless daily mean land surface temperature generation
- Enhancement of annual temperature cycle model by combining reanalysis data.
- Design a framework (IADTC framework) to generate physically true daily mean land surface temperature by combining the diurnal and annual temperature cycle models.
- Generate global daily mean LST from 2003 to 2019 and characterize the global LST trend.
- Validate the generated products with widely-distributed in-situ measurements.
- The code of the IADTC framework is available at: IADTC github. The generated dataset is freely available at zenodo.

[4] Evaluations of diurnal land surface temperature cycle (DTC) models under clear-sky
- Obtain nine representative four-parameter DTC models with a set of parameter-reduction strategies.
- Comprehensive assessment of the DTC models with geostationary satellite data and in-situ measurements.
- Provide the parameter-reduction order and the best-performance four-parameter DTC model.
- The examples of the DTC models are available at: DTC github.
- Related publication: Hong et al., 2008.
