Data associated with "Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms"

Data provided by  National Institute of Standards and Technology

Data associated with the publication: "Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms"Abstract:The ability to image electromagnetic fields holds key scientific and industrial applications, including electromagnetic compatibility, diagnostics of high-frequency devices, and experimental scientific work involving field interactions. Generally electric and magnetic field measurements require conductive elements which significantly perturb the field.

The U.S. Greenhouse Gas and Air Pollutant Emissions System (GRA2PES)

Data provided by  National Institute of Standards and Technology

To bridge the gap between the development of greenhouse gas (GHG) and air quality (AQ) emission inventories, we developed the GReenhouse gas And Air Pollutant Emissions System (GRA2PES), which provides self-consistent GHG and AQ emissions over the contiguous U.S. This inventory provides emissions at 4 km x 4 km spatial resolution with year, month, day-of-week, and diurnal temporal information. GRA2PES utilizes datasets from the U.S. Energy Information Administration (EIA) and the U.S.

Data for "Evaluating CO2 and CH4 absorption models with open-path dual-comb spectroscopy"

Data provided by  National Institute of Standards and Technology

Open-path near-IR dual-comb spectra collected at Mauna Loa Observatory in spring 2021, fit with different absorption models (eg HITRAN) and compared against NOAA GML's record.

Rydberg Atom Electrometry: Recent Sensitivity and Bandwidth Improvements

Data provided by  National Institute of Standards and Technology

We present recent improvements within the growing field of Rydberg atom sensors. While initially started as a path towards absolute, independent measurements of electric fields, the research landscape has evolved into the realm of quantum sensors and receivers. We discuss the capabilities and limitations of Rydberg atom receivers, and we show how different atomic properties enhance or limit sensitivity and bandwidth.This data is for a review paper. Figures 6 (a) and 8 (a) and (b) are new data. The rest of the data is extracted from other NIST publications that have a data management plan.

Dataset presenting improved bandwidth in Rydberg atom electrometry with an optical frequency comb probe

Data provided by  National Institute of Standards and Technology

Rydberg atom-based receivers of modulated radio frequency (RF) fields are promising systems for measurements. These systems are self-calibrating, widely tunable, nearly transparent to RF fields, and can be electrically small. However, the instantaneous bandwidth of current Rydberg atom receivers is typically less than 1 MHz.

Dataset demonstrating feasibility of two-ladder sensing approach

Data provided by  National Institute of Standards and Technology

Datasets included in manuscript on simultaneous two-ladder sensing, titled "Independent Rydberg Atom Sensing using a Dual-Ladder Scheme" to be submitted to Applied Physics Letters. The data for figure 1 contains experimental EIT traces for both ladders, and figure 2 contains the data for false-color plots showing the polarization-specific response of each ladder.

Data and code for the paper, "Inverse Transform Sampling for Efficient Doppler-Averaged Spectroscopy Simulations"

Data provided by  National Institute of Standards and Technology

This dataset represents the results of calculations of atomic absorption spectra for the case of two-color EIT. We compare computation methods, specifically Gaussian sampling, to find that one sampling method converges to smooth transmittance curves in less time than the other. We also include some example scripts which generate and plot the figure data.

Data for the paper "EIT spectra of Rydberg atoms dressed with dual tone radio-frequency fields"

Data provided by  National Institute of Standards and Technology

This dataset contains the data for the figures in the paper "EIT spectra of Rydberg atoms dressed with dual tone radio-frequency fields", submitted to Physical Review A. This dataset can be used to recreate the experimental and theory plots from the CSV files. The data show EIT spectra of Rydberg atoms driven with dual-tone RF fields (experimental), and Floquet spectra of numerical models that are used to model these EIT spectra (theory/numerical).

Hestia Fossil Fuel Carbon Dioxide Emissions Inventory for Urban Regions

Data provided by  National Institute of Standards and Technology

Hestia Fossil Fuel Carbon Dioxide Emissions Inventory for Urban Regions (Hestia FFCO2) provides data products for Los Angeles Basin, Northeast corridor, Indianapolis, and other U.S. Cities. Hestia FFCO2 datasets quantify greenhouse gases (GHG), such as carbon dioxide, emitted by urban regions, since cities are major contributors of anthropogenic GHG emissions. The Hestia FFCO2 datasets provide high spatial and temporal resolution CO2 concentrations at sub-county resolutions and annual/hourly time scales, specific to the region.
