This dataset is a collection of East coast winter storm simulations under NSF support for one 7 Feb 2020 Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Storms (IMPACTS) Field Campaign event.

Also present are five CSV files containing the IMPACTS aircraft observations assimilated into these experiments.

The file structure is as follows:
(^ indicates "as above"; ... indicates "and so forth")

Observation files: 1.7 KB
WRF Output Files: 4,018 GB

Naming Convention for Files:

For AIR and CONV:
    [Background Step] wrfinput_d[0X]_[yyyy]-[MM]-[dd]-[hh]:[mm]:[ss]_[ZZZ]
    [Analysis Step] wrf_enkf_output_d[0X]_[ZZZ]
For AIR-F, CONV-F, and NODA:
    wrfout_d[0X]_[yyyy]-[MM]-[dd]-[hh]:[mm]:[ss]

"d" is followed by 2 digits for the domain number (01, 02)

"ZZZ" is the 3-digit ensemble member number (000-040)

"yyyy" is the 4-digit year
"mm" is the 2-digit month
"dd" is the 2-digit day
"hh" is the 2-digit hour
"mm" is the 2-digit minute (always 00)
"ss" is the 2-digit second (always 00)

All files are in model height.
