Rijiju has thanked the IMD scientists for their relentless dedication.
The Ministry, along with the IMD, has released the findings of a committee that was put in place to examine the abnormal temperature reading at Mungeshpur on May 29.
According to the IMD, the Automatic Weather Station (AWS) at Mungeshpur reported a maximum temperature of 52.9 degrees C, and a committee chaired by a senior scientist, comprising other experts from the weather agency, was tasked to review the anomaly.
Their probe included an evaluation of the AWS sensor at Mungeshpur and comparisons with other AWS in Delhi, and the findings revealed a positive bias in the readings, with the said sensor reporting temperature approximately 3 degrees higher than standard instruments during the peak temperature period.
There were no significant discrepancies found in the readings reported by the other AWS stations in the national capital.
The committee has recommended several measures to be taken regarding the AWS and quality control before uploading the observed data from the AWS for the general public and various users.
