I am using GLEAMS v3.7b in my project and intend to use its soil moisture products. However, I am confused as to what are the depths for which the surface and root zone soil moisture products are computed.
I read the paper by Martens et al. (2017): https://gmd.copernicus.org/articles/10/1903/2017/gmd-10-1903-2017.pdf
This paper states that the depth of the root zone is a function of the land-cover type and comprises three model layers for the fraction of tall vegetation (0–10, 10–100, and 100–250 cm), two for the fraction of low vegetation (0–10, 10–100 cm), and only one for the fraction of bare soil (0–10 cm).
I am unable to comprehend as to how I should interpret this information. If the grid location of my data falls in an a forested area (tall vegetation), should I consider that the depth of root zone at that point is 250 cm as there will be three model layers?
Kindly provide some insight upon this. Thank you!

Based on the information provided in the paper by Martens et al. (2017), the depth of the root zone soil moisture products computed by GLEAMS v3.7b varies depending on the land-cover type. For areas with tall vegetation, the root zone comprises three model layers for the fraction of vegetation between 0–10, 10–100, and 100–250 cm depths. For areas with low vegetation, the root zone comprises two model layers for the fraction of vegetation between 0–10 and 10–100 cm depths. And for bare soil areas, the root zone only comprises one model layer for the fraction of soil between 0–10 cm depth.
Therefore, if your data grid location falls in a forested area (tall vegetation), you should consider that the depth of the root zone at that point is between 0-250 cm, with the fraction of vegetation being distributed over these three layers. However, it is important to note that the actual depth of the root zone may vary depending on several factors such as soil type, topography, and climate, and may not necessarily correspond to the model layers used by GLEAMS v3.7b.
please recommend my reply if you find it useful . Thank you
Aahed Alhamamy Thank you for your response. I know that the root zone of the soils in my area extend upto 100cm.
