Obtain IR diffuse data from WISE
Assuming you have downloaded their software from the link you provided and have astropy installed, you should be able to do:

from wssa_utils import wssa_getval
from astropy import units as u
from astropy.coordinates import SkyCoord

# Declare your wanted point in Galactic co-ordinates
c = SkyCoord(l=0, b=30, unit=(u.deg,u.deg), frame='galactic')
ra = c.icrs.ra
dec = c.icrs.dec
vals = wssa_getval(ra, dec)


The results look like they will be in MegaJanskys per steradian, which would be u.MJy/u.sr in astropy units.
For UV data, I'm not sure what is best, maybe GALEX ?
