  abstract = {{S}imultaneously acquiring time series of climate, hydrology and hydrochemical data over decades on river systems is pivotal to understand the complex interactions involving rock, soil water, air and biota in the {C}ritical {Z}one, to build integrated modelling and to propose predictive scenarios. {A}mong the {C}ritical {Z}one {O}bservatories ({CZO}s) implemented in the past 25 years, only a few are located in the humid {T}ropics despite the importance of these regions in terms of population density, fast-changing land use, biodiversity hotspots, biomass stock on continents, size of river systems, etc. {S}ince 1994, weathering and erosion processes and fluxes have been investigated at both local (experimental watershed) and regional scales in the {N}yong {R}iver {B}asin ({C}ameroon) which belongs to the {C}ritical {Z}one {O}bservatories network named {M}ultiscale {TROPI}cal {C}atchment{S} ({M}-{TROPICS}). {T}he data shared by {M}-{TROPICS} in {C}ameroon are: (1) rainfall; (2) air temperature, air relative humidity, wind speed and direction, and global radiation; (3) stream and river water level; (4) p{H}, electrical conductivity, water temperature and suspended particulate matter ({SPM}) concentration; (5) major ion, alkalinity and dissolved organic carbon ({DOC}) concentrations. {T}he dataset already contributed to describe the water partitioning in these tropical humid watersheds, to better understand the factors controlling chemical weathering and physical erosion in tropical ecosystems, particularly the role of organic matter. {T}he dataset also contributed to calculate elemental weathering fluxes and saprolite production rate and to propose denudation rates on tropical cratonic landscapes. {H}ydrological modelling allowed quantification of the geographical water sources contributing to streamflow. {DOC} data were used to determine greenhouse-gas emissions and carbon budgets from {A}frican inland waters. {H}owever, long-term solute concentrations at the outlet of a small tributary of the {N}yong {R}iver exhibit non-stationary behaviour over the last 26 years. {T}he processes governing those fluctuations are not yet fully understood and might be related to changes in the hydrological regime, land-cover and land-use. {T}he latter highlights the need for longer time-series and continued support for {CZO}s particularly in the humid tropics.},
