+ + This sample dataset presents a fine scale precipitation analysis from the development of NLDAS-3. NLDAS-3 is currently under development and the final product will include precipitation fields (included here) as well as other surface meteorology such as temperature, radiation, surface pressure, and wind speed. NLDAS-3 represents the next generation (i.e., phase 3) of the North American Land Data Assimilation System phase 2 (NLDAS-2). NLDAS-3 precipitation has been derived by assimilating daily precipitation amounts at 4 km of the NASA Integrated Multi-SatellitE Retrievals for Global Precipitation Measurements GPM (IMERG) and the Environment and Climate Change Canada (ECCC) Canadian Precipitation Analysis (CaPA) into the NASA’s Modern-Era Retrospective analysis for Research and Application, Version 2 (MERRA-2). NLDAS-3 precipitation at 4 km and daily time steps was then downscaled to 1 km using a cloud-cover based algorithm based on datasets from the Moderate Resolution Imaging Spectroradiometer (MODIS) then converted to hourly using a temporal disaggregation which employs MERRA-2 and IMERG datasets. NLDAS-3 covers North and Central America (from latitude 7 to 72 North and longitude 169 to 52 West) at a resolution of 0.01. The sample data available from this page are monthly-averages and an initial version of the still-in-development of the NLDAS-3 precipitation. + + ## Source Data Product Citation + Maina et al., (2024), NLDAS-3 surface meteorology 0.01 degree x 0.01 degree V1, Greenbelt, MD, USA, NASA Center for Climate Simulation (NCCS) DataPortal, Accessed: [Data Access Date] + + ## Version History + V2.0 + + + + + + ## Key Publications + Maina et al., (2024), NLDAS-3 surface meteorology 0.01 degree x 0.01 degree V1, Greenbelt, MD, USA, NASA Center for Climate Simulation (NCCS) DataPortal, Accessed: July 24, 2024. + + Bratseth.

These estimates are critical for drought and flood monitoring, water availability and water resource management, climate assessments, and other uses. For instance, the University of Nebraska-Lincoln’s [National Drought Mitigation Center](https://drought.unl.edu/) (NDMC) relies on NLDAS data for their drought assessments published weekly in the [U.S. Drought Monitor](https://www.drought.gov/data-maps-tools/us-drought-monitor). Applications like [OpenET](https://etdata.org/) and [QuickDRI](https://quickdri.unl.edu/) also rely on the quality of NLDAS meteorological forcing and model outputs. The phase 2 of NLDAS (NLDAS-2) is currently operational at NOAA, with long-term archives of data back to Jan 1979 available from NASA. +
+ + + NASA 2023 stakeholder workshop participant responses to the question, “How do you use NLDAS?” + +
+ + + + + + ## Community-Centered Model Development + Building on stakeholder feedback and advancements in Earth observations and data assimilation, teams across NASA are working on major enhancements to the NLDAS environment called “NLDAS Phase 3” (NLDAS-3). The vision for NLDAS-3 is to provide near field scale (~1 km), high quality, observation-informed estimates of land surface and hydrology conditions. Specifically, NLDAS-3 aims to: + - Improve the spatial resolution by providing meteorological forcing and land-surface model output at 1-km resolution; + - Expand the spatial coverage to encompass all of North and Central America, including Alaska, Hawaii, and Puerto Rico (see figures below); + - Utilize high quality surface meteorological data; + - Reduce the current NLDAS-2 latency of 3.5 days to near real-time; + - Upgrade the land surface model to include the latest scientific advancements, such as improved representation of groundwater processes (He et al., 2023); and + - Incorporate observational constraints by assimilating remote sensing datasets, which can help capture human management of water and vegetation, such as irrigation, groundwater withdrawal, droughts, floods, and hydrological impacts of wildland fire and other disturbances + +
+ + + Spatial domain of NLDAS-2 (CONUS) vs. NLDAS-3 (North and Central America). + +

+
+
+ + To make these improvements, science and modeling teams across NASA centers are using the open source NASA Land Information System (LIS) framework (Kumar et al., 2006; Peters-Lidard et al., 2007), a state-of-the-art software suite for high performance terrestrial hydrology modeling and data assimilation. LIS software is open-source and available at [GitHub](https://github.com/NASA-LIS/LISF). +
+ + +
+ + + + + + ## Precipitation Data Updates + NASA is updating NLDAS precipitation by leveraging NASA’s reanalysis and remote sensing data products. Specifically, we are working on a new data assimilation approach used successfully in operational environments as well as advanced optimal interpolation techniques (Kemp et al. 2022) to blend well-known and widely used precipitation datasets. Daily precipitation amounts at 4 km of the NASA Integrated Multi-SatellitE Retrievals for GPM (IMERG; Huffman et al. 2020) and the ECCC Canadian Precipitation Analysis (CaPA; Lespinas et al. 2015) are assimilated into NASA Modern Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2; Gelaro et al. 2017) precipitation data. Then the precipitation analysis at 4 km is downscaled to a 1 km fine-scale resolution using a cloud cover frequency-based algorithm and disaggregated into hourly using IMERG and MERRA-2 datasets. Below are examples of NLDAS-2 and NLDAS-3 precipitation data over North America to illustrate improved spatial resolution of NLDAS-3 data. + + + +
+ + + + NLDAS-2 and NLDAS-3 precipitation outputs for August 2017. +
+ + + + ## Data Browser + Users are encouraged to further examine the NLDAS-2 and sample NLDAS-3 precipitation using the following two data catalogs links. They contain monthly-averaged precipitation from both products for a ~20-year period. Click on “Explore Data” in the upper right of these two data catalogs. + - NLDAS-2 + - NLDAS-3 + + + + + + ## Explore the Data in the Cloud + Below are links to sample monthly precipitation forcing data in Jupyter Notebooks for you to further explore and examine NLDAS-2 and the sample NLDAS-3 data. + - [Notebook 1](https://nasa-impact.github.io/veda-docs/notebooks/datasets/nldas_time_series.html) shows you how to create time series for NLDAS-3 data. + - [Notebook 2](https://nasa-impact.github.io/veda-docs/notebooks/datasets/nldas_compare2_3.html) shows you how to compare NLDAS-2 and NLDAS-3 data. + + + + + + ## Surface Meteorology Data Updates + The other NLDAS-3 meteorological forcings are obtained by downscaling MERRA-2 datasets (except for Shortwave Down radiation, which will use CERES/POWER data) using the methods as follows: + +
