Help With NOAA Reports

[The Dalek Hunter]

Stupid question coming - sorry.

I have never paid much attention to the NOAA reports other than to check they are working. Having a look at them today for one on my sites

https://www.angteck.co.uk/noaareport.htm

I notice a -18.0

Temperature (°C), Heat Base: 18.3 Cool Base: 18.3
Dep. Heat Cool Max Max Min Min
Mean Mean From Deg Deg >= <= <= <=
YR MO Max Min Mean Norm Days Days Hi Date Low Date 27.0 0.0 0.0 -18.0

Being stupid - what does the -18.0 represent. I have gone into the Dashboard and looked at all time records, monthly records but can't find a -18.0 anywhere.

Thanks

The lines have to read together...

Code: Select all

                          Dep.  Heat  Cool                       Max  Max  Min  Min
        Mean  Mean        From  Deg   Deg                        >=   <=   <=   <=
 YR MO  Max   Min   Mean  Norm  Days  Days  Hi  Date  Low  Date 27.0  0.0  0.0 -18.0

So that column is a count of the number of days where the temperature equalled or dropped below -18.0
