@mod, calculate daily climatology

It’s time for using higher time resolution.

Defining time axis with daily time scale is the point.

ref1(daily), ref2(for monthly)

1. Defining a daily axis and calculating daily climatology

yes? DEFINE AXIS/T/=0:365.2425/EDGES/NPOINTS=365/T0=1-JAN-0001/UNITS=DAYS/MODULO tdaily
yes? LET dailyclim = udaily[GT=tdaily@MOD]

2. Also you can calculate anomaly

yes? let anomaly = udaily – dailyclim[gt=udaily@asn]

So, Simple 🙂
