Re: The spectral response Table of PACE HARP2 includes negative values
Hello, the following are the answers to your questions. Hope it helps. 1) Negative values other than –99 These are observed negatives that passed the initial filtering. If a value exceeded the 3-sigma uncertainty, it was retained as potentially real (even if negative). Values within 3-sigma were mas...

Re: PACE-OCI and Aqua-MODIS FLH algorithms and validations
Hello Tian, Apologies for the delayed response. Compared to MODIS, the PACE OCI nFLH algorithm uses additional bands — specifically nLw(650, 660, 710, and 720), versus nLw(667 and 748) for MODIS. The ATBD and corresponding validation are still under development, so we appreciate your patience as we ...

Re: Replacement Browser for Decommisioned Browser Level 1 & 2
Hi Len, The near real-time (NRT) Kd490 data is included in the MODISA_L2_OC_NRT collection on NASA Earthdata Search. You can search and download granules there. For more efficient data access, I recommend using the Python package earthaccess, which streamlines searching and downloading L2 data. Here...
