SMAPVEX19-21 Massachusetts Vegetation Optical Depth V001
As part of the SMAPVEX19-21 campaign, an L-band radiometer was deployed on top of a tower at Harvard Forest,Massachusetts, looking down at a stand of red oak forest. The radiometer collected data in V-polarization from late April to mid October 2019. Over 4 days in early July 2019, the water potential and L-band complex dielectric constant of canopy leaves were measured at various times of day. Other instruments were installed within the radiometer's field of view to measure soil moisture and temperature, air temperature, tree xylem apparent dielectric permittivity at 70 MHz, tree xylem water potential, and canopy wetness. The goal of this experiment was to study the sensitivity of L-band vegetation optical depth (VOD) to changing vegetation water potential over a growing season.

- Type: ECHO ORDERSDescription: NSIDC_ECS EOSDIS ECHO ORDERS Service Implementation
- Type: EGI - No ProcessingDescription: Using this service, data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, or through our Application Programming Interface (API). This API offers you the ability to programmatically order and bulk-download data using temporal and spatial filters without the need to script against NSIDC's data directory structure. This may be valuable if you are interested in incorporating data access commands into your analysis or visualization code.
- Type: NOT PROVIDEDDescription: Allows users to download select NSIDC Earth Observing System (EOS) DAAC data directly via HTTPS. Products are available from AMSR, AMSR-E, ASO, Aquarius, HMA, IceBridge, ICESat/GLAS, ICESat-2, MEaSUREs, MODIS, NIMBUS, NISE, Passive Microwave, SnowEx, SMAP and VIIRS.
- Type: Web User InterfaceDescription: A search interface providing users the ability to search amongst all data sets cataloged by NSIDC.
- Type: Downloadable ToolDescription: A Jupyter notebook exploring data coverage, size, and customization service availability along with direct data download utilizing the NSIDC DAAC's Data Access and Service API.
- Type: Web User InterfaceDescription: NASA Earthdata Search is a map-based interface where users can search for Earth science data, filter results based on spatial and temporal constraints, and when available, order data with customizations including re-formatting, re-projecting, and spatial and parameter subsetting. Thousands of Earth science data sets are accessible from 12 science-oriented Distributed Active Archive Centers (DAACs). The NSIDC DAAC distributes several hundred data sets in NASA Earthdata Search, many with customization options.
- Type: Web User InterfaceDescription: Search and filter data files for a given data set using a map-based interface. Data filtering options include filename wildcard, start and end date, and spatial area as bounding box, polygon, or geospatial file import.Show MoreShow Less
