What is Gldas?
The goal of the Global Land Data Assimilation System (GLDAS) is to ingest satellite- and ground-based observational data products, using advanced land surface modeling and data assimilation techniques, in order to generate optimal fields of land surface states and fluxes (Rodell et al., 2004a).
What is Gldas runoff?
The GLDAS Runoff layer is a time-enabled image service that shows average monthly runoff from 2000 to the present measured in millimeters. The model is run with 3-hourly time steps and aggregated into monthly averages.
What is Noah land surface model?
Product. Noah-MP is a land surface model (LSM) using multiple options for key land-atmosphere interaction processes (Niu et al., 2011). Noah-MP contains a separate vegetation canopy defined by a canopy top and bottom, crown radius, and leaves with prescribed dimensions, orientation, density, and radiometric properties.
What is merra data?
MERRA is an abbreviation for Modern Era Retrospective-Analysis for Research and Applications. The dataset originates from the Global Modeling and Assimilation Office of NASA / Goddard Space Flight Center. The MERRA analysis are being conducted with the GEOS-5 Atmospheric Data Assimilation System(ADAS).
What is Noah LSM?
RAL scientists work to understand, through theoretical and observational studies, the complex biophysical, hydrological, and bio-geochemical interactions between the land-surface and the atmosphere at micro- and mesoscales.
What is merra 2 model?
MERRA-2 is the first long-term global reanalysis to assimilate space-based observations of aerosols and represent their interactions with other physical processes in the climate system. MERRA-2 includes a representation of ice sheets over (say) Greenland and Antarctica.
How do I download ERA5 data?
3 – Downloading online ERA5 family data through the CDS web interface
- Go to the C3S climate data store (CDS).
- Type ‘ERA5’ in the search box.
- Follow the ERA5 dataset title link of interest (there will be many more hits).
- Currently there are eight online ERA5 and two ERA5-Land catalogue entries.
What is Noah MP model?
Noah-MP is a land surface model (LSM) using multiple options for key land-atmosphere interaction processes (Niu et al., 2011). Noah-MP contains a separate vegetation canopy defined by a canopy top and bottom, crown radius, and leaves with prescribed dimensions, orientation, density, and radiometric properties.
Is merra 2 a satellite?
MERRA-2 is also the first satellite-era global reanalysis to assimilate space-based observations of aerosols and represent their interactions with other physical processes in the climate system.
What is the resolution of ERA5?
ERA5 data will be at a much higher resolution than ERA-Interim: hourly analysis fields will be available at a horizontal resolution of 31 km on 137 levels, from the surface up to 0.01 hPa (around 80 km).
What is ERA5 data?
ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. The data cover the Earth on a 30km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km.
What is NASA merra?
The Global Modeling and Assimilation Office’s (GMAO) Modern Era-Retrospective Analysis for Research and Analysis (MERRA) is a NASA reanalysis using a modern satellite data and the Goddard Earth Observing System Data Assimilation System Version 5 (GEOS-5).
