Short Name:

AA_L2A

AMSR/ADEOS-II L2A Global Swath Spatially-Resampled Brightness Temperatures V001

The AMSR Level-2A product (AA_L2A) contains brightness temperatures at 6.9 GHz, 10.65 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, 89.0 GHz, 50.3 GHz, and 52.8GHz. Data are resampled to be spatially consistent except for the 50.3GHz and 52.8GHz data, and therefore are available at a variety of resolutions that correspond to the footprint sizes of the observations such as 56 km, 38 km, 24 km, 21 km, 12 km, and 5.4 km, respectively.

NSIDC_ECS_ECHO_ORDERS View Service Record
Type: ECHO ORDERS
Description: NSIDC_ECS EOSDIS ECHO ORDERS Service Implementation
NSIDC_ECS_EGI_API_NO_PROCESSING View Service Record
Type: EGI - No Processing
Description: 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.
NSIDC_ECS_DAAC_HTTPS_File_System View Service Record
Type: NOT PROVIDED
Description: 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.

NSIDC_ECS_DATA_ACCESS_NOTEBOOK View Tool Record
Type: Downloadable Tool
Description: 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.
NSIDC_ECS_Data_Search View Tool Record
Type: Web User Interface
Description: A search interface providing users the ability to search amongst all data sets cataloged by NSIDC.
NSIDC_ECS_NASA_Earthdata_Search View Tool Record
Type: Web User Interface
Description: 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.
NSIDC_ECS_Data_Access_Tool View Tool Record
Type: Web User Interface
Description: 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.
