Daily plots of noise levels for each AIRS channel are available on the AIRS webpage at https://airs.jpl.nasa.gov/mission/instrument-operations/.
A link there currently points to where the files are hosted at https://thunder.jpl.nasa.gov/nedt_trends/html/airs_channel_nedt_trends.html.
For each channel there are plots for the whole AIRS mission and for the last 2 months.
Going forward, weekly Ops status updates will be archived at the same webpage above,
