Day-degree, or Degree day | Variation of one degree per day in mean daily temperature, above an adopted standard reference temperature (usually 10oC). The number of degree days for a single day is the actual variation of mean temperature from the standard. The number of degree days is a month, or other interval, is the sum of daily values. When the mean temperature on a given..... | | Similar Terms |

Water salinity | The presence of dissolved ions in water. May refer to ground water, soil water or to water supplies for domestic, industrial or agricultural uses. Generally water can be used without restriction for any such purpose if salinity is below some threshold value, but as salinity increases above the threshold, its use is restricted as it begins to cause ..... | | Similar Terms |
