This dataset contains gridded daily surface reflectance and brightness temperatures derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) sensors onboard NOAA polar orbiting satellites. Surface reflectance from VIIRS channels I1, I2, and I3 (at 640, 865, and 1610 nm) are a NOAA Climate Data Record (CDR). The dataset spans from 2014 to 10 days before the present, and was processed from the VIIRS 375m and 750m Earth view Sensor Data Record (SDR) datasets.

This dataset contains gridded daily Normalized Difference Vegetation Index (NDVI) derived from the NOAA Climate Data Record (CDR) of Visible Infrared Imaging Radiometer Suite (VIIRS) Surface Reflectance. The data record spans from 2014 to 10 days before the present using data from NOAA polar orbiting satellites. The data are projected on a 0.05 degree x 0.05 degree global grid. This dataset is one of the Land Surface CDR products produced by the NASA Goddard Space Flight Center (GSFC) and the University of Maryland (UMD).

The product is the aerosol optical thickness (AOT) at 0.63 micron, which is retrieved from NOAA PATMOS-x AVHRR+HIRS level-2B orbital radiance and cloud CDR products. The retrieval is performed for selected spatial (0.1 by 0.1 degree) and temporal (1 time per day per satellite) resolution in cloud free conditions during daytime. The final product is daily averaged from all satellite retrievals and in a 0.1 by 0.1 degree equal angle grid (total 1800x3600 grids over the globe).

*This version has been superseded by a newer version. It is highly recommended for users to access the current version. Users should only access this superseded version for special cases, such as reproducing studies. If necessary, this version can be accessed by contacting NCEI.* The NOAA Global Surface Temperature Dataset (NOAAGlobalTemp) is a blended product from two independent analysis products: the Extended Reconstructed Sea Surface Temperature (ERSST) analysis and the land surface temperature (LST) analysis using the Global Historical Climatology Network (GHCN) temperature database.

The central components of this dataset are satellite passive microwave observations centered on tropical cyclones from imagers such as AMSR2, AMSR-E, AMSU-B, ATMS, GMI, MHS, SSM/I, SSMIS, and TMI. These observations include 1) multi-channel microwave brightness temperatures inter-calibrated across all the available imagers using GMI and 2) outputs from NASA's Goddard Profiling Algorithm such as retrieved surface precipitation rate, convective precipitation rate, vertical profiles of rain water and snow water content, and vertically-integrated ice water content.

A G-AIRMET is a graphical advisory of weather that may be hazardous to aircraft, but are less severe than SIGMETs. They are valid at specific time "snapshots". The G-AIRMET forecasts are distributed in XML (USWX) format. The USWX XML files contain forecaster-created graphical objects which depict hazard areas and attributes. G-AIRMETs are issued at discrete times 3 hours apart for a period of up to 12 hours into the future (00, 03, 06, 09, and 12 hours). They are issued at 03:00, 09:00, 15:00 and 21:00 UTC (with updates issued as necessary).

The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) is the world's most extensive surface marine meteorological data collection. Building on national and international partnerships, ICOADS provides a variety of user communities with easy access to many different data sources in a consistent format. Data sources range from early historical ship observations to more modern, automated measurement systems including moored buoys and surface drifters.

Global Historical Climatology Network-hourly (GHCNh) is a multisource collection of weather station (meteorological) observations from the late 18th Century to the present from fixed weather stations over land across the globe. It is replacing the Integrated Surface Dataset (ISD) and will be used to generate the Local Climatological Data and Global Summary of the Day datasets. It is constructed to align with GHCN daily. Version 1 contains approximately 110 separate data sources and will be updated daily using the United States Air Force and NOAA Surface Weather Observations data streams.

This dataset covers the IR Sounder Upper Trop Humidity BT CDR that is based on the high-Resolution Infrared Sounder (HIRS) suite of intersatellite calibrated channel 12 brightness temperature (BT) and from the Infrared Atmospheric Sounding Interferometer (IASI) measurement that is used to derive equivalent HIRS channel 12 BT. The channel is designed to measure upper tropospheric humidity. Cloud-screening is performed and clear-sky pixels are used to generate the product. The time series has a global coverage in monthly 2.5x2.5 degree latitude/longitude from 1978 to the present.

This dataset contains the Marine Optical Buoy (MOBY) ancillary (deployment) files. These are HTML pages which have auxiliary data associated with each data set in the deployment. The data file formats are in text (ASCII) and HTML. The images are in JPG and PNG formats; they are not compressed. The time period covered by the MOBY ancillary (deployment) dataset begins at 1997-07-29. The project is ongoing and continuous. More data is added as updates to the data record become available.
