+
+	* ARTS-XML-DATA-2-1-42
+
+	* planets/Earth/ERA40/*.gz,readme.txt:
+	Made all fields clearly cyclic (adding lon=360deg as duplicate of
+	lon=0deg). Adapted readme accordingly.
+
+	* planets/Earth/Fascod/tropical/tropical.[t,z].xml:
+	Added additional point at p=1100hPa in consistency with all other
+	arts-xml versions of fascod atmospheres (the were commited to
+	ARTS-XML-1-1 in this version years ago...) and to facilitate few-hundred
+	meter negative altitudes. Done with assuming a constant temp. below z=0m
+	and hydrostatoc equilibrium. Equivalent point-adding still needs to be
+	done for the tropical trace gas profiles (also as vmr=const at z<0km).
