| Abstract | PGE16 6.5.18 A char array size was properly adjusted to account for the size of the log string being passed to the "SMFLOG" function. |
| Problem Statement | Current operational version of PGE16 (V6.5.17) was failing with memory "Buffer out of bounds" error since the switch to the Ubuntu OS. |
| Description of Change | A char array size was properly adjusted to account for the size of the log string being passed to the "SMFLOG" function. |
| Products Affected | Daily L2/L3 LST products, MxD11_L2/MxD11B1/A1 |
| Software Affected | PGE16 6.5.18 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing. |
| Downstream Product Effects | No direct impact on any downstream LST products, though this change will ensure the continuity of the MxD11 L2 and L3 daily products. |
| Data Granules to be Used for Science Testing | Ran test in AS 1912 for several days and the PGE16 was confirmed to run and produce science quality data by LDOPE and MODAPS. |
| Justification | The PGE16 v6.5.17 was failing in production with a memory error, since the switch to Ubuntu, for occasional granules. Hence, it had to be fixed to continue with nominal production. |
| Effective Date for Implementation of Change | PGE16 V6.5.18 was placed in forward production since 09/28/2022. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved on 10/13/2022. Sudipta Sarkar approved on 10/13/2022. |
