Journal of Remote Sensing Special Issue
Radiation Transfer Modeling With Radiation Transfer Model Intercomparison Vegetation Canopies
Journal of Remote Sensing, a Science Partner Journal, is now considering submissions for its second special issue, Radiation Transfer Modeling With Radiation Transfer Model Intercomparison Vegetation Canopies.
Physically based radiation modeling is increasingly used to study radiation reflectance, emissions and energy budgets of urban and natural Earth surfaces. Such modeling is essential for advancing the interpretation of existing satellite remote sensing (RS) observations in terms of geoscience parameters of our planet, but also for designing new RS satellite missions aiming to study urban climate and vegetation functioning. Depending on their scientific objectives, models can be more or less detailed and, consequently, computationally complex. Models can be designed to be universal (ie, able to simulate all radiative events taking place between the radiation source and the sensor) or specialized (ie, focusing on a specific component of the Earth system such as radiative transfer [RT] in the atmosphere, vegetation canopies, bodies of water, and more). Simpler large-scale models are often parametric, with calibration and parametrization originating from the ground and RS observations or potentially from outputs of more complex models. This results in a great diversity of existing RT models and associated input parameters and output end products.
In order to benchmark and improve their performance, the RT modeling community participates in the RAdiation transfer Model Intercomparison (RAMI) exercise, organized by the Joint Research Centre (JRC) of the European Commission (EC) since 1999. Its first four phases (RAMI-I to RAMI-IV) aimed to compare modeled reflectance and radiative budget products of abstract and actual vegetation canopies, which contributed greatly to improvements in accuracy, robustness and function of participating models. The last phase (RAMI-V) started in October 2020. It offers new ways to compare and further improve RT models by simulating abstract and actual scene definitions of the RAMI-IV phase, as well as two new actual 3D scenes of a pre-fire two-layer (trees and grass) savanna ecosystem in the Kruger National Park (South Africa) and the Wytham Wood deciduous forest (United Kingdom).
This special issue of Journal of Remote Sensing aims to publish results related to the RAMI-V phase. It is open to scientists who directly participate in RAMI-V, but also to those who use RAMI-I to RAMI-V vegetation canopies to model various RS data in other spectral and research domains, including (but not limited to) thermal infrared RS, terrestrial and airborne LiDAR or solar-induced chlorophyll fluorescence observations. The special issue will illustrate the broad potential and computational efficiency of the state-of-the-art radiation models for simulating RS observations and the radiative budget of abstract and actual vegetation canopies. It will also help identify gaps and burn needs in radiation modeling science. For this special issue, contributions of unpublished original research based on RAMI-V vegetation canopies are expected. Prospective authors are encouraged to document their modeling approaches and results in the following and related research domains:
- RT modeling and simulations realized in the frame of the RAMI-V phase
- Modeling of BOA and TOA remote sensing observations (eg, radiometer, LiDAR, etc.) and radiative budget of RAMI vegetation canopies in short and long wavelengths (including solar-induced fluorescence)
- Validation of RT models
- High-speed computational implementations of RT simulation codes
- Innovative applications of RAMI RT simulations for remotely sensed data analysis and interpretation (including model inversions)
- Engineering tools for a remote sensing instrument design developed based on RAMI-V scenes
