Yes, this is a correct way.
The logic is to find the pixels with valid cloud fraction values for both Cloud_Mask_Fraction_Low and Cloud_Retrieval_Fraction_Liquid, then for these pixels you can use either Cloud_Retrieval_Fraction_Liquid or Cloud_Mask_Fraction_Low.

Tyler,
Thanks very much for the quick action. I review these and will get back to you asap.

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...

Looking into it and will get back to you soon.

We just tried a query like you were trying and could not reproduced your error. We could order data without any issue (see attached). You may want to retry after clearing your browser's history or can try in another browser.

The SDS "Cloud_Effective_Radius_1621" is "Cloud Particle Effective Radius two-channel retrieval using band 7(2.1um) and band 6(1.6um)from best points". For more information see: https://atmosphere-imager.gsfc.nasa.gov/products/cloud/format-content and https://atmosphere-imager.gs...

We are glad that you find our data archive on the Cloud useful. No, currently there is no plan to migrate MODIS L1A data to the Cloud.
