  We construct a one-dimensional (1D) topological SSH-like model with chiral
symmetry and a superimposed hopping modulation, which we call the chiral
Aubry-Andr\'e model. We show that its topological properties can be described
in terms of a pair (C,W) of a two-dimensional (2D) Chern number C, stemming
from a superspace description of the model, and a 1D winding number W,
originating in its chiral symmetric nature. Thus, we showcase for the first
time explicit coexistence of 1D and 2D topology in a model existing in 1D
physical space. We detail the superspace description by showcasing how our
model can be mapped to a Harper-Hofstadter model, familiar from the description
of the integer quantum Hall effect, and analyze the vanishing field limit
analytically. An extension of the method used for vanishing fields is provided
in order to handle any finite fields, corresponding to hopping modulations both
commensurate and incommensurate with the lattice. In addition, this formalism
allows us to obtain certain features of the 2D superspace model, such as its
number of massless Dirac nodes, purely in terms of topological quantities,
computed without the need to go into momentum space.
