description: Albedo files

    1. File Naming Convention: albedo-{m}-{s}.nc        m: Represents the month of the data.        s: Represents the LULC (Land Use/Land cover) scheme.             It can take one of the following values:                LCCS1,LCCS2,LCCS3,IGBP    2. Albedo Variables:        Albedo variables follow the naming convention: albedo-{w}-{b}-{t}, where:            w: Represents the type of albedo, which can be:                WSA: White-sky albedo (diffuse incoming solar radiation).                BSA: Black-sky albedo (direct beam solar radiation).            b: Represents the spectral band:                shortwave: Refers to the shortwave band.                nir: Refers to the near-infrared (NIR) band.                vis: Refers to the visible light band.            t: Represents LULC type of LULC scheme s.        The albedo is stored in a 20*180*360 matrix, representing years (2001-2020), latitude, and longitude.    3. Area Variables:        Area variables follow the naming convention: area-{t}, where:            t: which can be:                Represents LULC type of LULC scheme s, or,                land:land area                grid:grid area        The area is stored in a 20*180*360 matrix, representing years (2001-2020), latitude, and longitude.    4. Quality  Variables:        Variables name: qa            condition:              1--grids have data              2--all ocean              4--SZA>85 and no data

Areas of LULC conversion files

    1. File Naming Convention: confuse_matrix_{y}_{s}.pth        y: Represents the year of the data.        s: Represents the LULC scheme.             It can take one of the following values:                LCCS1,LCCS2,LCCS3,IGBP    2. Array data        Data is a 4D matrix: (m,lat,lon,t1,t2)            The area of LULC type t1 to t2 conversion,             from 2001-m to y-m ,             within the 1-degree grid at (lat, lon).                        Size:12*180*360*num-t*num-t, where:            m: Represents months.            lat: Latitude.            lon: Longitude.            t1/t2: LULC types for each LULC scheme:                LCCS1: landtype 1-15 + snow.                LCCS2: landtype 1-10 + snow.                LCCS3: landtype 1-9 + snow.                IGBP: landtype 1-16 + snow.
