The Infrared Radiation (IR) Sounder Upper Tropospheric Humidity Brightness Temperature (BT) Climate Data Record (CDR) measures upper tropospheric humidity. High Resolution Infrared Radiation Sounder (HIRS) level-1b data, in conjunction with cloud-clearing, limb-correction, and inter-satellite calibration, provide the CDR input. The final record has global coverage at a 2.5°x2.5° spatial resolution and provides data from 1978–present.
To help the project receive continued support, updates, and improvement, tell us how you use IR Sounder Tropospheric Humidity BT CDR data by completing our optional User Registration Form.
