Validation of [3D]-RTMA AIRCFT Data Generated Using the bufr2ioda

[PraveenKumar-NOAA]

Description

• The purpose of this issue is to validate the [3D]-RTMA AIRCFT data generated using the YAML in #1359

• The output NetCDF file is generated using the following BUFR file/subset: rtma_ru.t0000z.aircft.tm00.bufr_d | NC004006 | A55200 | MTYP 004-006 Automated European AMDAR (BUFR) |

• The input BUFR and output NetCDF file will be plotted using Python and other tools, and statistical analysis will be performed for the comparison

• The temperature and wind obs will be used for the validation

Requirements

• bufr2ioda.x
• Plotting script(s) to plot BUFR and NetCDF files

Acceptance Criteria (Definition of Done)

• Agreement between the BUFR and NetCDF data

Dependencies

• There are no dependiencies

@MatthewMorris-NOAA @nicholasesposito please check these validation plots for the [3D]-RTMA AIRCFT data.

[MatthewMorris-NOAA]

The plots look good!

[nicholasesposito]

Looks good to me!

[PraveenKumar-NOAA]

A few more validation plots were created using the following AIRCFT subset:

• NC004103 --- MTYP 004-103 All other automated AMDAR (BUFR)

Temperature plots: BUFR and IODA:

Wind plots: BUFR and IODA:

Looks good

[MatthewMorris-NOAA]

The plots look good. Do you know why there are a few more obs in the IODA figures?

@MatthewMorris-NOAA thanks, these number of obs are probably less than 0.05% in IODA figures and I think this is due to some of the variables type change, like an integer to float conversion.

@MatthewMorris-NOAA A few more validation plots that were created using the ioda-converters [3D]-RTMA AIRCAR YAML and for the following subset:

NC004004 --- MTYP 004-004 Automated MDCRS (ARINC to NCEP) (BUFR)

Temperature plots: BUFR and IODA:

Wind plots: BUFR and IODA:

[MatthewMorris-NOAA]

Overall, the figures look good. My only question is why there are fewer obs in the BUFR wind speed figure relative to the other figures?

[PraveenKumar-NOAA]

@MatthewMorris-NOAA thanks, I will check it out.

[PraveenKumar-NOAA]

@MatthewMorris-NOAA the length of wind data is 77074 in bufr data, which is similar to what listed in ioda plot above. There are a total of 137 missing values in wind data and are not counted into the bufr plot.

wind= [4.6] wind= [9.3] wind= [--] wind= [1.] wind= [3.1]

The statistics are same in both plots, hence there are no issues with the aircar yaml and validation plots.

@PraveenKumar-NOAA Thanks for the info! Looks good!
