SIR

I'VE DOWNSCALED FUTURE YEARS 2016-2050 OF GCM 'GFDL-ESM2M' UNDER RCP8.5.. AFTER OPENING THE OUTPUT FILE IN GRADS BY ISSUING THE COMMAND:-

 ./Bin/GrADSNcPlot output/test_001_SRF.2021010100.nc

GRADS SAYS:-

LON set to 54.58 83.84
LAT set to 19.88 38.36
LEV set to 0 0
Time values set: 2021:1:1:3 2021:1:1:3
E set to 1 1

HERE THE TIME (IN BOLD) IS SOMETHING STRANGE.. THAT IS WHEN I ISSUE THE FOLLOWING COMMAND:-

ga-> q time

it says

Time = 03Z01JAN2021 to 03Z01JAN2021  ??? to ???


THEN I SET

ga-> set t 1 30

Time values set: 2021:1:1:3 2021:1:4:18

ga-> Time = 03Z01JAN2021 to 18Z04JAN2021  ??? to ???


My question is:-

1. IS THIS NECESSARY TO SET THE TIME TO 30 DAYS (ga-> set t 1 30) SO THAT GRADS CAN GENERATE DAILY DATA (30 DAYS) FOR THE MONTH OF JAN ??

2. WHY THE TIME (ABOVE IN BOLD) SHOWS ONLY 4 DAYS (01JAN-04JAN) AND NOT 30 DAYS (01JAN-30JAN) ??
