| sfc | Surface level |
| sfc[100] | surface level with 100 mb above surface layer average (parcel trajectory) |
| sl | Sea level |
| frz | Freezing level |
| lcl | Lifted condensation level (LCL) |
| sea | Sea surface |
| mwnd | Maximum wind level |
| trop | Tropopause level |
| top | Top of the atmosphere (not used) |
| whole | Whole atmosphere |
| top_frz | Top most freezing level |
| lcld_bot | Bottom of low cloud layer |
| lcld_top | Top of low cloud layer |
| lcld_lyr | Low cloud layer |
| mcld_bot | Bottom of middle cloud layer |
| mcld_top | Top of middle cloud layer |
| mcld_lyr | Middle cloud layer |
| hcld_bot | Bottom of high cloud layer |
| hcld_top | Top of high cloud layer |
| hcld_lyr | High cloud layer |
| conv_bot | Bottom of convective cloud layer |
| conv_top | Top of convective cloud layer |
| conv_lyr | Convective cloud layer |
