Many thanks for posting this - I've never seen it before. Please could you
post the data for 160m and 6m as well if you have it, to complete the list?

the quietest locations at the quietest time of the year are:
>80 m 38 dB
>40 m 33 dB
>20 m 28 dB
>15 m 23 dB
>10 m 18 dB
>This is according to CCIR surveys. The receiver NF should be 6-10 dB lower.
