 == Getting data from ECMWF ==
+The standard data I provide is from ECMWF's operational data. It is a deterministic forecast from the atmospheric model, version 1, analysis. It is not ERA.
+Data prior to X is in GRIB1 format, after that it is GRIB2.  The GRIB start dumps are created by concatenating the following fields:
+
+ * skin temperature,
+ * surface pressure,
+ * land-sea mask,
+ * geopotential,
+ * temperature,
+ * specific humidity,
+ * U and V wind velocities
+
+In contrast a UM dump contains typically a hundred fields.  So the GRIB start dumps need to be reconfigured.
