Subject:	GAN/PBLHT/M1-Oceanic Site Planetary Boundary Layer Heights (PBLHs) from Radiosondes - Possible Issue
DataStreams:	ganpblhtsonde1mcfarlM1.s1
Description:	Automated methods for estimating PBLHs from radiosonde data may in some instances be identifying shallow stable layers over island surfaces as the PBLH. Insufficient data exists at this time to modify the automated algorithms to resolve this situation. Reported oceanic site PBLHs of <100 m, particularly at night, should be used with caution.
Measurements:	ganpblhtsonde1mcfarlM1.s1: Planetary boundary layer height above mean sea level calculated by Liu and Liang (2010) method(pbl_height_liu_liang) Planetary boundary layer height above mean sea level calculated from bulk Richardson number using critical threshold of 0.25(pbl_height_bulk_richardson_pt25) Planetary boundary layer height above mean sea level calculated using the Heffter (1980) method(pbl_height_heffter) Planetary boundary layer height above mean sea level calculated from bulk Richardson number using critical threshold of 0.5(pbl_height_bulk_richardson_pt5)
