attribute	blank_reference_578	comment	String	Optical absorbance reference intensity at 578 nm. Measured with deionized water. Reference and signal intensities range between 0 and 4096. Values should be greater than ~1500. Lower intensities will result in higher noise in the absorbance and pH measurements. Obtained from the reference_light_measurements variable in the Data Portal sourced data file. Values are fill values for measurements > 3.
