Validation of HY-2A data
Proposal To address the problem of inadequate sea surface winds and keeping the objective of failure free and accurate monitoring of severe weather events, it is proposed to develop a mosaicking of sea surface winds derived from various polar orbiting satellites. (Oceansat 2, ASCAT & HY 2A)
Mosaicking of sea surface winds of Oceansat-II, ASCAT and HY-2A satellites. OSCAT Data ASCAT Data HY 2A Data 17:22 UTC, 09 Oct 2013 15:44 UTC, 09 Nov 2013 08 Aug 2012
Methodology/Implementation 1. Identification of sources and their consent to share the data. 2. Collection of the data. 3. Standardisation of the format. 4. Quality analysis 5. Development of software. 6. Development of Mosaic. 7. Validation. 8. Real time implementation through creation of website.
Time schedule Total Time:3 years 1 st Year: Identification of sources and collection of data 2 nd year: Quality analysis, development of software & mosaic 3 rd year: Validation, real time implementation & preparation of report.
Institutional commitments for sustained product generation Implementing Agency India Meteorological Department (IMD) India Collaboration The project will be implemented in collaboration with EUMETSAT & NOAA.
