As a result, the computed GHT at the subset of levels is based on GHT on the missing levels with corrupt GHT values.Īfter memory allocation of TT and QV, force array initialization to zero. A vehicle identification number (VIN) is a unique code assigned to every motor vehicle when it's manufactured. Calc_ecmwf_p.exe computes the GHT from level to level, starting at the lowest level 137. Since the subsequent pre-processing utility mod_levs.exe removes all levels except for the subset of levels, one could argue that the GHT data at the subset of levels should be correct as the GHT data is only corrupt at the missing levels. This leads to corrupt temperature and specific humidity data being transferred to the hypsometric equation, which results in corrupt GHT data. A VIN check will tell you literally everything there is to know about your specific vehicle so you can feel safe on the road. It is also a good idea to run a VIN check on whatever vehicle you own, whether Hyundai or otherwise, and especially if you purchased a used vehicle. Now, memory allocation does not mean array initialization to zero! It can happen that the value at (1,1) is unequal to zero, meaning that the level is regarded as 'valid'. A VIN check will inform you if there is a current recall on your specific Hyundai vehicle Final Thoughts. Missing levels are identified by looking at the TT-value at the first gridpoint (1,1) being equal to zero. The program computes the TT and QV at the missing levels using linear interpolation. Feeding a subset of the 137 levels into calc_ecmwf_p (we only have 24 levels), means that not all levels in the 3D array are filled.
The program allocates memory for TT and QV 3D arrays and fills these arrays with input data. For that, the temperature (TT) and specific humidity (QV) are required.Ĭalc_ecmwf_p.exe computes the GHT at all 137 ECMWF hybrid levels, and needs TT and QV at all these levels.
The geopotential height (GHT) is calculated using the hypsometric equation ( ). Some models with default PIN code: Nissan Altima 2001-2004. The corrupt GHT fields obviously result in erroneous WRF forecasts or even a crash of WRF. For (C) and (L) try to calculate the PIN code by SEC label, BCM to PIN (software), BCM to PIN (online), Dump to PIN or PIN code by BCM seed (20 chars code) for newest Nissan models. The problem occurs as we feed to calc_ecmwf_p only a subset of levels (24) we receive operationally from ECMWF. We encountered corrupt GHT datafields provided by calc_ecmwf_p.exe.
