The relationship between concentrations of chl-a calculated from SeaWiFS OC2 and chl-a calculated determined from ground truth measurements during field expeditions in Lake Baikal during 2001 and 2002

Values of measured chlorophyll (HPLC=High Pressure Liquid Chromatography) are the mean concentrations of each sampling point from 5 to 30 m depth. For the OC2 chl-a calculations, the least clouded acquisitions in 2001 (2001/07/19) and 2002 (2002/07/20) were chosen. Note the considerable chl-a overestimation caused by the influences of terrigenous input in case 2 waters.

经高效液相色谱法（High Pressure Liquid Chromatography，HPLC）测定的叶绿素浓度，为各采样点在5米至30米水深的平均浓度。针对OC2叶绿素a（chlorophyll-a，chl-a）的计算，选取了2001年（2001/07/19）与2002年（2002/07/20）云量最少的遥感影像。需注意，二类水体（case 2 waters）受陆源输入的影响会导致叶绿素a出现显著的高估现象。
