Product Suite: Surface Reflectance --Polarization correction, de-trending and gain adjustments of Terra and Aqua L1B --Improvement to the aerosol retrieval and correction algorithm, and use of new aerosol retrieval LUTs--Refinements to the internal snow, cloud, and cloud shadow detection algorithms. Uses BRDF database to better constraint the different thresholds used.--Process ocean bands and provide QA datasets for these bands--Improved discrimination of salt pans from cloud and snow and flag salt pan in band QA.

Product Suite: Thermal Anomalies and Active Fire--Refinements to internal cloud mask, which sometimes flags heavy smoke as clouds--Fix for frequent false alarms in the Amazon that are caused by small (~1 km2) clearings within forests--Fix to correct a bug that causes incorrect assessment of cloud and water pixels adjacent to fire pixels near the scan edge--Detect small fires using dynamic thresholding--Process ocean and coastline pixels to detect fire from oil rigs.

Product Suite: Sea-ice --No change to the science algorithm.

Product Suite: Land Surface Temperature and Emissivity--Remove cloud-contaminated LSTs not only from L3 LST products but also from L2 LST products.--Update the coefficient LUT for the split-window algorithm with comprehensive regression analysis of MODIS simulation data in bands 31 and 32 over wide range of surface and atmospheric conditions, especially extending the upper boundary for (LST -- Ts-air) in arid and semi-arid regions and increasing the overlapping between various sub-ranges in order to reduce the sensitivity of the algorithm to the uncertainties in the input data (i.e., column water vapor and air surface temperature from MxD07).--Make minor adjustments in the classification-based surface emissivity values, especially for land-cover type of bare soil and rocks.--Tune the day/night algorithm by adjusting weights to improve its performance in desert regions where the incorporated split-window algorithm may not work well.--Generate new LST products for 8-day and monthly at 6 km grids (in response to user community requests).

Product Suite: Vegetation Indices--Generates 16-day composite VI using two 8-day composite reflectance product (MxD09A1) in the 16-day period.--This Surface Reflectance Input is based on the Minimum Blue compositing approach used to generate the 8 day LSR product--Product format is consistent with the C5 version of the product generated using the L2G daily surface reflectance product.--Update to the Long term Global CMG Average Vegetation Index Product database used to fill the gaps in the CMG product suite

Product Suite: BRDF/Albedo--Generated daily, still using the 16-day composite algorithm.--Observations are weighted to estimate the BRDF/Albedo at the first day of the 2nd 8-day period of the 16-day period.--Uses improved back up database -- pixel based updated from latest full inversion as opposed to the land cover based DB used in C5.--Improved quality and more retrieval at high latitudes from use of all available observations. C5 used only four observations per day.--Uses current day snow status instead of the majority snow/no-snow status from the 16-day period.--CMG Albedo is estimated through retrieval of albedo using all the clear sky observations within 1 km grid for MCD43D as opposed to aggregating from 500 m albedo--Uses L2G-lite surface reflectance as input

Product Suite: LAI/FPAR--Uses daily L2G-lite surface reflectance as input as opposed to MODAGAGG used in C5--Products are generated at native resolution of 500 m--Uses improved multi-year land cover product

Product Suite: GPP/NPP--Uses updated BPLUT and updated version of the daily GMAO--Generate product at native resolution of 500 m using the 8-day composite LAI/FPAR at 500 m resolution

Product Suite: Gridding and L2G products--Better geolocation accuracy

Product Suite: Snow Cover--Generates C5 snow as input to the downstream processes: L2 snow for LST and L3 daily snow for BRDF/Albedo

Product Suite: Burned Area Intermediate--Improvement to the quality filtering algorithm and additional quality flags

Product Suite: VCF Intermediate--No changes

Product Suite: L1 Subsets--AERONET and FLUXNET subset updated to include additional sites--New set of subsets generated for over 400 sites called the "BELMANIP" sites.

Product Suite: GIBS and WMTS Imagery--New in C6 to support generation of imagery for GIBS and WMTS--L2 granules and L3 tiles are projected into tiles in geographic projection, before converting to images using the color LUTs provided by the science team.
