# Value of density parameters in CMB time

I was looking for the value of the density parameters ($$\Omega_{i}$$) in cosmology at the time of decoupling (CMB Time).

I know that the Planck Colaboration aproximatelly gives $$\Omega_{m}=0.315$$, $$\Omega_{\Lambda}=1-\Omega_{m}$$. But those are given at the present time.

I know that i can infer them doing some calculations but I prefer to have a measured value.

The quoted cosmological parameters are just that - in the framework of the $$\Lambda$$CDM FRW universe, their values at one epoch imply their values at any epoch.
I am not sure but I have never seen such data in articles or books etc. However, you can use a cosmological calculator to find the value at $$z\approx 1100$$
