M2T1NXSLV (atau tavg1_2d_slv_Nx) adalah kumpulan data 2 dimensi yang dirata-ratakan per jam dalam analisis Retrospektif Era Modern untuk Riset dan Aplikasi versi 2 (MERRA-2). Kumpulan data ini terdiri dari diagnostik meteorologi pada tingkat vertikal yang umum digunakan, seperti suhu udara pada 2 meter (atau pada 10 meter, 850 hPa, 500 hPa, 250 hPa), komponen angin pada 50 meter (atau pada 2 meter, 10 meter, 850 hPa, 500 hPa, 250 hPa), tekanan permukaan laut, tekanan permukaan, dan total uap air yang dapat diendapkan (atau air es, air cair). Kolom data diberi stempel waktu dengan waktu tengah
satu jam yang dimulai dari 00.30 UTC, misalnya: 00.30, 01.30, ... , 23.30 UTC.
MERRA-2 adalah versi terbaru analisis ulang atmosfer global untuk era satelit yang diproduksi oleh NASA Global Modeling and Assimilation Office (GMAO) menggunakan Goddard Earth Observing System Model (GEOS) versi 5.12.4. Dataset ini mencakup periode 1980 hingga saat ini dengan latensi sekitar 3 minggu setelah akhir bulan.
