====== Comparison of Ground-Based and GEOS-R Fog and Low Stratus Observations over North Dakota ======

===== Reports =====
February 22, 2022: Submitted Report Progress - Limited progress in the first month.  We have setup the project management tasks and started to select case dates from conducting the comparison.  Have worked on extracting the visibility data set from our CHORDS data base system.  Next tasks will be to download satellite data for the dates selected.

April 6, 2022: The data for the December 15, 2021 fog event in Fargo, ND has been collected.

April 22, 2022: The data for the October 28, 2021 fog event in Fargo, ND has been collected.

June 28, 2022: Satellite data for each fog event, thus far, has been collected and put in its respective folders. Waiting for Satellite script to be fixed (it works fine for Christian but does not work on computers in Clifford 422). Time Series data has not been collected yet because Alex does not know where to get CS125 data for Grand Forks fog events when the MetTrailer was in Fargo.
===== Data Collections =====
The photos and data sets collected for this project are saved at /nas/Surface/Analysis/

In this path, there are individual fog event folders and a folder with each script used for this project:

**1. Data:**
GOES-R FLS data from the NOAA website (https://www.avl.class.noaa.gov/saa/products/search?sub_id=0&datatype_family=GRABINDE&submit.x=33&submit.y=13) is of the product 'GOES-R Series ABI L2+ Enterprise Roducts (Grabinde)'. Each data set is sent to the requester as separate .nc files with four to five minutes of data within each one.
  * Datatype: ABI Fog/Low Stratus
  * Satellite: G16
  * ABI Scan Sector: CONUS

GOES-R Satellite data from the NOAA website (https://www.avl.class.noaa.gov/saa/products/search?datatype_family=GRABIPRD) is of the product 'GOES-R Series ABI Products (GRABIPRD) (partially restricted L1b and L2+ Data Products)'. Each data set is sent to the requester as separate .nc files with four to five minutes of data within each one.
  * Datatype: ABI L1b Radiance Data
  * ABI Channel: C02
  * Product Type: Radiance
  * ABI Scan Sector: CONUS
  * Satellite: G16

Visibility surface observations from ASOS/METAR (https://mesonet.agron.iastate.edu/request/download.phtml?network=ND_ASOS#) database on the Iowa State website. Files provided are .csv and used in the IFR/LIFR plots and comparison graphs.
  * Station/Network: One file with all stations in North Dakota for IFR/LIFR plots and another file with the nearest city to the fog event for comparison graphs.
  * Data: Visibility [miles]
  * Timezone: Coordinated Universal Time (UTC)
  * Data Format: Comma Delimited
  * Include Latitude + Longitude: Yes
  * Save result data to file on computer

CS125 visibility sensor mounted on the MetTrailer (http://mettrailer.atmos.und.edu/). Data downloads as one large .csv file.
  * Datatype: Last Visibility (mi)
  * 5 minute interval

Camera data of the fog event from the deeplens cameras mounted on the MetTrailer. 

**2. Results:**
Comparison of GOES-R FLS observation with surface observations during the Fog event (maps and time series focusing mainly on area where the fog event occured).

**3. Scripts:** 
Scripts can be run when in Aircraft on Linus Terminal. (ssh -p 22000 aircraft.atmos.und.edu)

"plot-map-IFR.py" is used for plotting ASOS visibility and NOAA IFR visibility.

"plot-map-LIFR.py" is used for plotting ASOS visibility and NOAA LIFR visibility
