+<h2>NOTES</h2>
+<h4>Quarter years</h4>
+The bioclimatic indices referring to the wettest, driest, warmest or 
+coldest quarter differ from the official Worldclim bioclimatic indices 
+because <em><b>r.bioclim</b></em> divides a year into four quarters, 
+whereas Worldclim divides a year into 12 quarters. In 
+<em><b>r.bioclim</b></em>, the first quarter refers to Jan - Mar, the 
+second quarter to Apr - Jun, and the last quarter to Oct - Dec. In 
+Worldclim, the first quarter refers to Jan - Mar, the second quarter to 
+Feb - Apr, and the last quarter to Dec - Feb. The reason is that 
+Worldclim assumes long-term averages as input, whereas 
+<em><b>r.bioclim</b></em> assumes long-term-averages or records for a 
+specific year, in which case it does not make sense to calculate a 
+quarter by combining December, January, and February.
