      Kar amiki,

      Me es serchanta tradukuro por la termini Angla "yesterday's heating degree
      days", "yesterday's cooling degree day" e "yesterday's growing degree days".

      Me parlektis l' artiklo infra, komprenis omno, ma ankore ne povis pensar pri
      bona tradukuro. Nun me tradukis:

      "Varmigo-gradala dii di hiere"
      "Koldigo-gradala dii di hiere"
      "Kresko-gradala dii di hiere"

      Saluti amikala,

      Hans St.
