Does anyone know why leaf area index value in era5 never change in many years?

I have downloaded the era5 Leaf area index vegetation low and high but when i extract the data from my work in different years to wacht the variation … The value still the same until 1950 to 2024. I use R to export the data to Raster but it still the same

Can any one help me what can i DO?

Hi, This is explained in Table 3 of ERA5: data documentation.
" Leaf Area Index (LAI) parameters are based on a monthly climatology. Users will only see monthly variability, but not inter-annual variability."

Hi Kevin, thanks for your help. i’ve read the data.documentation.

I have downloaded single month and i compare it to the same month but in different year . It still the same value … I try do to export the data in R and Python but it give me the same value… So my code is not enough or can you give me some advice to export the data. (I have already downloaded another parameters but it work i have the variation)

Thank you

Hi, the same monthly climatology is used for each year, so you will not see any differences comparing the same month from different years,
Thanks, Kevin
