+# Keep in mind rule for input ../cmor/cmip6-cmor-tables/Tables/*.json:
+#    output variables can not contain "_" in out_name, though name (and standard_name) itself can have it; example:
+#        "alb_sfc": {
+#            "frequency": "mon",
+#            "modeling_realm": "atmos",
+#            "standard_name": "alb_sfc",
+#            "units": "percent",
+#            "cell_methods": "area: time: mean",
+#            "long_name": "surface albedo",
+#            "comment": "",
+#            "dimensions": "longitude latitude time",
+#            "out_name": "albsfc",
+#            "type": "real",
+#            "positive": "",
+#            "valid_min": "",

+# Problems with standard CMOR library:
+#   - monthly variable "enth_conv_col" produces error - CMOR expects 4 dimensions but it has only 3;
+#   - variable /archive/oar.gfdl.cmip6/CM4/warsaw_201710_om4_v1.0.1/CM4_historical/gfdl.ncrc4-intel16-prod-openmp/pp/atmos_cmip/ts/3hr/5yr/atmos_cmip.1965010100-1969123123.clt.nc
