I am trying to write a sentence such as,
" we are measuring the CO2 level accurately in the atmospherethan we have ever before / than we did ever before."
Which one can be used ? or none of them ?
Do you mean:
We are measuring the CO2 level in the atmosphere more accurately than we have ever done before
