Dear all,
we are trying to improve the representation of land use information in the regional climate model WRF for 1. aquaculture and 2. rice paddies in the Mekong River region (Vietnam). The major question is which existing land use class (from MODIFIED_IGBP_MODIS_NOAH classification) corresponds best to those?
If none of the predefined classes is suitable, we could add new classes to the LANDUSE.TBL, but we would need the parameters from experiments or from literature, i.e. albedo (ALBD %), soil moisture (SLMO × 100%), surface emissivity (SFEM %), surface roughness length (SFZ0 × 10 −2 m), thermal inertia (THERIN × 4.184 × 10 2 J/m 2 Ks 1/2 ), and surface heat capacity (SFHC × 10 6 J/m 3 K) for aquaculture and rice paddies, respectively.
Thank you very much for all kind of helpful suggestions.
Cheers, Patrick

In the MODIFIED_IGBP_MODIS_NOAH classification, there are several land use classes that may be suitable for representing aquaculture and rice paddies in the Mekong River region of Vietnam.
For aquaculture, the most suitable class may be "Crop lands, irrigated" (class 3). This class represents lands that are used for intensive cropping and are irrigated, which may be similar to the characteristics of aquaculture systems. However, it may also be helpful to consider creating a new class specifically for aquaculture, using parameters such as those you listed (albedo, soil moisture, etc.) that are relevant to this type of land use.
For rice paddies, the most suitable class may be "Rice paddies" (class 5). This class represents lands that are used for growing rice and are typically flooded or irrigated, which is similar to the characteristics of rice paddies. However, it may also be helpful to consider creating a new class specifically for rice paddies, using parameters such as those you listed (albedo, soil moisture, etc.) that are relevant to this type of land use.
It is worth noting that the optimal land use class will depend on the specific characteristics of the aquaculture and rice paddies in the Mekong River region, and it may be helpful to consider using a combination of predefined classes and new classes to accurately represent these land uses in the WRF model. Additionally, it may be helpful to consult with experts in the region or refer to literature on aquaculture and rice paddies in Vietnam to ensure that the selected land use classes and parameters accurately reflect the characteristics of these land uses.
Dear Patrick,
For aquaculture, you can consider using the "Cropland/Natural Vegetation Mosaic" class in the MODIFIED_IGBP_MODIS_NOAH classification, as it can represent areas with both natural vegetation and croplands. You may also want to consider adding a new class for aquaculture, as it is not represented in the existing classes.
For rice paddies, you can consider using the "Cropland/Grassland Mosaic" class, as it can represent areas with both croplands and grasslands. Again, you may also want to consider adding a new class specifically for rice paddies.
As for the parameters, you can try looking for literature on land surface parameterization for aquaculture and rice paddies, or conduct your own experiments to determine the parameters for your specific study area. It is important to note that the parameters may vary depending on the specific type of aquaculture or rice paddy, as well as the local climate and soil conditions.
I hope this helps! Good luck with your research.
