Monthly aggregated Water Vapor MODIS MCD19A2 (1 km): Monthly time-series (2003-2005)
<p>This data is part of the <em>Monthly aggregated Water Vapor MODIS MCD19A2 (1 km)</em> dataset.

MCR LTER: Coral Reef: Optical parameters and SST from SeaWiFS and MODIS, ongoing since 1997 and AVHRR-derived SST from 1985 to 2009
Monthly averages of the Sea Surface Temperature (SST), the Sub-surface chlorophyll-a concentration (Chl), the colored dissolved and detrital organic materials at 443 nm (acdm[443]) and the particulate backscattering coefficient at 443 nm (bbp[443]) around Moorea are obtained or derived from satellite data (SST from AVHRR and MODIS-Aqua; Chl, acdm[443] and bbp[443] from SeaWiFS and MODIS-AQUA). The satellite data are averaged over a 1 month period for geographic areas of 16S-19S/147W-151W (SeaWiFS and MODIS-AQUA) and 15S-20S/145W-155W for AVHRR. This material is based upon work supported by the U.S. National Science Foundation under Grant No. OCE 16-37396 (and earlier awards) as well as a generous gift from the Gordon and Betty Moore Foundation. Research was completed under permits issued by the French Polynesian Government (Délégation à la Recherche) and the Haut-commissariat de la République en Polynésie Francaise (DTRT) (Protocole d'Accueil 2005-2022). This work represents a contribution of the Moorea Coral Reef (MCR) LTER Site.

Global leaf chlorophyll content (LCC) product from MODIS imagery (2000-2020)
<p>The spatial and temporal distribution of leaf chlorophyll content (LCC) is critical for understanding the capacity of vegetation photosynthesis.

Global Daily Surface Blue-sky Albedo Climatology and Land Cover Climatology Dataset from 20-year MODIS Products (CMG)
<p>Surface albedo plays a critical role in climate, hydrological, and biogeochemical modeling and weather forecasting. Therefore, precisely mapping surface albedo climatology globally is necessary to better parameterize environmental systems. We generated a new global surface blue-sky actual and snow-free albedo climatology dataset from 20-year MODIS products from the Google Earth Engine (GEE). </p> <p>The 500m global surface blue-sky daily albedo climatology dataset is available at .... After reprojection and aggregation, the global Climate Modeling Grid (CMG) albedo climatology datasets at 0.05° and 0.5° are available here. All of the published datasets include historical and snow-free blue-sky albedo climatology data. For application convenience, the land cover climatology of MODIS product (MCD12Q1) is also generated and attached in the CMG files. The International Geosphere-Biosphere Programme (IGBP) and PFT classification results of MCD12Q1 since 2001 were reprojected and aggregated to 0.05° and 0.5° by find mode in each aggregation group. In order to check the heterogeneity of the land cover climatology, the percentage of the dominant type in each aggregation group was also calculated.</p>
