Satellite images (10x10 pixels) centered at Folsom, CA (lat=38.642N, lon=121.148W)

<p>Satellite images centered on Folsom, CA&nbsp;(lat=38.642N, lon=121.148W).</p> <p>This dataset includes images&nbsp;from GOES-15, which operated as GOES-West from 2011 until February 2019, when it was superseded by GOES-17.<br> The Earth-facing imager on GOES-15 has five spectral bands: one visible band centered at 0.63<span class="math-tex">\(\mu m\)</span> and four infrared bands centered at 3.9, 6.5, 10.7, and 13.3<span class="math-tex">\(\mu m \)</span>, respectively.</p> <p>This data includes&nbsp;measurements from the visible band (VIS), which has a spatial resolution of 1.0 km and a temporal resolution of one image every 30 minutes.</p> <p>Each image of 10 pixels x 10 pixels is flattened into a vector&nbsp;<span class="math-tex">\(\tilde{x}\)</span>. Each image is then normalized as</p> <p><span class="math-tex">\(x_i = \frac{ \tilde{x}_i-\text{avg}(\tilde{x})}{\sqrt{ \text{var}(\tilde{x})+10}}\)</span></p> <p>where&nbsp;<span class="math-tex">\(\tilde{x}\)</span>&nbsp;is the&nbsp;unprocessed 8 bit grayscale image vector, avg&nbsp;is the arithmetic mean value, and var is the variance.</p> <p>Each line in the csv file corresponds to a single image.<br> The first column is the image timestamp in UTC.<br> The values that follow the timestamp correspond to&nbsp;100 normalized gray-scale values obtained using the algorithm described above.</p> <p>&nbsp;</p>
