Supported Datasets

Supported models and observations are below. Please see Adding New Datasets for advice on how to add new model and observational datasets to MELODIES MONET.

Supported Models

WRF-Chem	Yes	Yes	TEMPO, MOPITT, TROPOMI
CESM/CAM-chem FV	Yes	Needs testing	MOPITT, MODIS, TEMPO

RAQMS	Yes	Needs testing	MOPITT, OMPS

In general, processing requires input to be in netCDF format. For the above models, scripts to configure the model data into a standard format for MELODIES MONET are available. If input datasets are in netCDF format and define latitude, longitude, pressure, and a datetime object, MELODIES MONET may be able to directly read the input files.

Please refer to the MELODIES MONET project board to learn more about our current and future development plans.

Supported Observations

Surface

To use these surface datasets in MELODIES MONET specify “obs_type” equal to “pt_sfc” in your YAML file. Currently, surface data in MELODIES MONET is paired horizontally using the nearest neighbor approach and temporally with exact time matching (e.g., if model data is provided hourly and observational data is provided hourly, these will pair together). More time interpolation options will be added in the future.

Available now:

AirNow - Air quality data aggregated by AirNow
AERONET - NASA AErosol RObotic NETwork
AQS - US EPA Air Quality System
ISH and ISH-Lite - NOAA National Centers for Environmental Information (NCEI) Global Hourly - Integrated Surface Database
OpenAQ - Global, aggregated, harmonized public air quality data hosted by OpenAQ

Under Development:

IMPROVE - Interagency Monitoring of Protected Visual Environments
CRN - U.S. Climate Reference Network
TOLNet - Tropospheric Ozone Lidar Network
CEMS - Air Emission Measurement Center (EMC) Continuous Emission Monitoring System
Pandora (Pandonia Global Network)

Please refer to the MELODIES MONET project board under milestone “Surface and Aircraft Evaluation Version 2” to learn more about our current and future development plans.

Note

The Command Line Interface can be used to download and create MELODIES MONET-ready datasets for: AirNow, AERONET, AQS, ISH, ISH-Lite, and OpenAQ.

Aircraft, Sonde, Mobile, and Ground Campaign Data

Pairing capabilities include time, horizontal, and vertical interpolation. Horizontal interpolation uses the nearest neighbor approach. Vertical interpolation uses linear interpolation and nearest neighbor for extrapolation with a warning if users are pairing points above the model top, which is not recommended. Users can evaluate aircraft data, ozonesonde data, mobile or walking data, and single ground site data. To use these options in MELODIES MONET specify “obs_type” equal to “aircraft”, “sonde”, “mobile”, or “ground” in your YAML file. The table below describes these options in more detail. Available datafile formats include NetCDF, ICARTT, and CSV.

Description of YAML File Options for “obs_type” For Campaign Data
“obs_type”	Description of Pairing
“aircraft”	Aircraft - Time, horizontal, and vertical interpolation across the entire dataset.
“sonde”	Sonde - Vertical interpolation across the entire dataset. Time and horizontal interpolation at a fixed release time and location.
“mobile”	Mobile - Time and horizontal interpolation across the entire dataset at the surface.
“ground”	Ground - Time interpolation across the entire dataset. Horizontal interpolation at a fixed location at the surface.

Tested datasets include the following:

FIREX-AQ - Fire Influence on Regional to Global Environments and Air Quality
ATom - ATmospheric Tomography Mission
SUNVEx - Southwest Urban NOx and VOC Experiment
AEROMMA - Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas
ASIA-AQ - Airborne and Satellite Investigation of Asian Air Quality
GML ozonesondes - NOAA Global Monitoring Laboratory (GML) ozonesondes

MELODIES MONET is written generally enough that other field campaign datasets should work well in the tool with minimal adjustments.

Satellite

MELODIES MONET supports evaluation against satellite observations for column-integrated and profile retrievals. Satellite data processing includes swath-to-grid regridding, quality filtering, and model pairing.

Available now:

MODIS - Moderate Resolution Imaging Spectroradiometer aerosol products (MOD04_L2, MYD04_L2). See MODIS Satellite Data for detailed documentation.
MOPITT - Measurements of Pollution in the Troposphere (CO profiles)
OMPS - Ozone Mapping and Profiler Suite
TROPOMI - TROPOspheric Monitoring Instrument (NO2)
TEMPO - Tropospheric Emissions: Monitoring of Pollution (NO2, HCHO)

To use satellite datasets in MELODIES MONET, specify obs_type as one of: sat_swath_clm, sat_swath_sfc, sat_swath_prof, sat_grid_clm, or sat_grid_sfc in your YAML file.
