"KEY POINTS
• BURGER is the first global IDF data set derived from observations of sub-daily rainfall
• Sub-daily rainfall intensities are computed with the Simplified Metastatistical Extreme Value (SMEV) approach for a range of return periods
• BURGER intensities compare well with expected intensities, indicated by an interquartile range of the percentage bias between −5% and 5%..”

In celebration of World Metrology Day this week (May 20), here's "The proclamation regarding weights and measures, 1556", a mural by Ford Madox Brown completed c.1893, depicting the announcement that the residents of Manchester "shall send in all manner of weights and measures to be tried by their Majesties standard". The announcement seems to be received about as well as you might expect.
Caption contest, anyone?

For examples, 1 #kg of liquid water at room termperature has 1 #litre of #volume. Therefore, 1 #tonne of water fits into a cube with sides of 1 #m. One #calorie is the amount of #heat or #energy required to raise the #temperature of 1 #gram (or 1 #cc or #CubicCentimetre) of water by 1 #degreeCelsius or 1 #K.
