-LYq Atmosphere Forcing
--------------------------
-
-The LYq (:cite:`Hunke07`) forcing was used in earlier standalone 
-runs on the gx1 grid, and the
-Consortium continues to do some very limited testing with this forcing dataset.
-This dataset is largely based on the CORE II data.
-Monthly average data for cldf and fsnow is read while 6-hourly data for Qa, Tair, 
-uatm, and vatm are read with other fields derived or set by default.
-Users are encouraged to switch to the JRA55 (see :ref:`JRA55forcing`) dataset. This
-atmosphere forcing dataset may be deprecated in the future.
