Re: How to select low level warm water cloud fraction in MODIS MCD06COSP dataset

Below is a response from our SME: Cloud Mask Fraction Low: it is based on cloud top pressure (CTP >= 680hpa) for daytime (SZA <= 85 deg). The daytime cutoff is less strict than cloud optical properties (SZA <= 81.3731 deg), so the data extends a bit farther poleward. It may include liquid, ice, or u...

Re: Scaling of Cloud Top Temperature product of MODIS Aqua level 2

The values you listed are correct. The "add_offset" value is a negative value: units = K scale_factor = 0.009999999776482582 add_offset = -15000.0 The following equation should be used to get to the real value: value = scale_factor * ( stored_value - add_offset ) so for a stored integer va...
