Topic: Metop-A MHS Channel 2 Failure Due to Noise Increase
Date/Time Issued: February 14, 2020 2258Z
Product(s) or Data Impacted: MHS Products
Date/Time of Initial Impact: November 15, 2019 0000Z
Date/Time of Expected End: Never

Impacts on Users and Significance: MHS products are affected.
Details/Specifics of Change:
The Metop-A MHS channel 2 has quickly degraded from Nov 2019 through January 2020. In
that time period, the NEDT changed from around 5K to around 20K, and the gain decreased
from around ten counts per Kelvin to two counts per Kelvin. As a result, this channel will be
declared as failed. Channel 2 L1b data will continue to be processed and made available along
with those of other Metop-A MHS channels.
